Quick Review Summary

The Frigidaire FFAD7033R1 70 Pint Dehumidifier with Effortless Humidity Control (White) is quite simply the best 70 pint dehumidifier we’ve tested and reviewed thus far, for a variety of reasons. First and foremost, it does best what a dehumidifier is designed to do – it removes moisture quickly and, just as importantly, it does so efficiently. Of the sixteen 70 pint dehumidifiers we’ve tested, it removed moisture more quickly than fourteen others in our first moisture removal test, and all other 70 pint dehumidifiers in our second moisture removal test.

It’s also very quiet, highly durable, notably adjustable, and surprisingly versatile. For a detailed description of its performance in each one of our four hands on performance tests, in addition to a thorough analysis of its features and functionality and how it compares to the other 70 pint dehumidifiers we tested – in other words, for detailed analysis – see our full review below. For a more complete summary of how this Frigidaire dehumidifier’s performance and features make it our #1 recommendation in the 70 pint dehumidifier category for 2020, see our final thoughts at the end of this review.

Note: This particular review was written several years ago, thus all comparisons within this review are made comparing this dehumidifier to the other relevant high capacity dehumidifiers at the time of its release, most of which are now discontinued. Also note that this dehumidifier, while a 70 pint unit at the time of its release, would be a 50 pint unit by today’s pints/day standards.

Some Notes Before We Start The Review

1. Our review of the FFAD7033R1 will involve comparisons to its predecessor, the FAD704DWD.

The FFAD7033R1 is only the latest 70 pint dehumidifier to be released by Frigidaire. Today, you can still very easily purchase the previous model, the FAD704DWD. We want to note here that (1) because both units are still readily available for sale and more importantly, (2) because we rated the FAD704DWD as one of the best dehumidifiers when it was first released, we’ll be comparing the FFAD7033R1 to the dehumidifier it’s replacing – the FAD704DWD – throughout this review.

Is the FFAD7033R1 a better option than the FAD704DWD? Are these two dehumidifiers essentially the same or does each offer unique features and functionality? Do we still recommend the FAD704DWD as the best dehumidifier for the most situations or does its replacement, the FFAD7033R1, now take the crown as the king of dehumidifiers? We’ll be answering these questions and more as we cover each dehumidifier’s features and functionality below. Rest assured, we’ll also be comparing the FFAD7033R1 to the other fifteen 70 pint dehumidifiers we’ve tested thus far throughout this review but we wanted to make it clear before get started that the fact that we’ll be comparing these two dehumidifiers, specifically, is not without good reason.

2. A brief history of recently released 70 pint Frigidaire dehumidifiers.

We also want to make an additional note about the FFAD7033R1′s “newness”. The truth is that it’s quite common for dehumidifier manufacturers to release new “updated” models quite frequently. Thus, it came as no surprise to us when Frigidaire decided to release the FFAD7033R1 in 2015, only two years after they released the FAD704DWD in 2013. The FAD704DWD was itself the successor to Frigidaire’s previous 70 pint offering, the FAD704DUD.

With the release of these three models we saw the release of a new Frigidaire 70 pint dehumidifier once every two years for six years. In order, in those six years, we saw the release of the FAD704DUD, the FAD704DWD, and then the FFAD7033R1. Each new iteration saw a variety of different modifications and upgrades. We were therefore quite eager to get our hands on the FFAD7033R1 when we first tested it in 2015. We were eager to see how it would measure up to its previous iteration – not only as far as features and functionality were concerned, but also in terms of its real world performance in our four hands on performance tests. We talk about its performance in these tests in detail in the review below.

Early 2020 Update: It appears Frigidaire has finally broken the cycle of releasing a new 70 pint dehumidifier once every 2 years. Now, in 2020, close to 5 years after its initial release, the FFAD7033R1 is still the latest flagship 70 pint Frigidaire dehumidifier.



Performance Test Results

Energy Efficiency

The FFAD7033R1 is an energy star rated dehumidifier with a manufacturer specified maximum power draw of 745 watts. The previous model, the FAD704DWD, has the exact same manufacturer specified maximum power draw of 745 watts. To better compare the power draw of these two units and also to better compare the power draw of all of the 70 pint dehumidifiers we tested, we conducted our own in house energy efficiency test. We set the test environment to approximately 50% relative humidity for each test and measured the power draw for each dehumidifier we tested under these conditions. What would our own tests show? Not surprisingly, both Frigidaire units also drew exactly the same amount of power in our in house energy efficiency test. The measured power draw for each unit was 632 watts at 50% relative humidity.

Compared to other 70 pint dehumidifiers we tested, this measured power draw of 632 watts is slightly above average, as ten out of the sixteen 70 pint units we tested had a measured power draw of 620 watts or less. Five units had a measured power draw of only 590 watts and the most energy efficient 70 pint dehumidifier we tested, the RCA RDH705, was measured to draw only 571 watts of power.

Power Draw Vs Moisture Removal Rate In Determining Energy Efficiency

You might be inclined to think that because the FFAD7033R1′s measured power draw was higher than average, that it is also less energy efficient than average. This, however, is simply not the case. As we discuss at the bottom of the page here energy efficiency is directly related to moisture removal rate (time). As you’ll see in our discussion of this unit’s moisture removal rate below, the FFAD7033R1 removed moisture much faster than most other 70 pint dehumidifiers we tested. Because it can dehumidify the same humid environment in less time, it is actually more “energy efficient” than any particular dehumidifier that is rated to draw less power but takes more time to dehumidify the same environment. That is to say that in any situation in which the dehumidifier is going to be running for an extended period of time, moisture removal rate will actually play a larger part in energy efficiency than base power draw. For this reason, we evaluated the Frigidaire’s moisture removal rate in addition to its power draw in assessing its energy efficiency compared to other 70 pint dehumidifiers we tested..

Manufacturer Specified Power Draw Vs Real World Power Draw

You might be confused as to why our in house testing resulted in a measured power draw that was considerably less than the manufacturer specified maximum power draw for all of the dehumidifiers we tested. The answer is rather simple. As humidity increases, so does power draw. In the simplest terms, the dehumidifier’s compressor has to “work harder” to dehumidify a very humid environment compared to a less humid environment. Our test environment wasn’t very humid, thus our testing resulted in lower numbers for measured power draw. Manufacturer specified power draw is more indicative of how much power the dehumidifier will draw at maximum capacity when dehumidifying an environment that is at maximum humidity (100% relative humidity).

Energy Efficiency Conclusion

So, in evaluating the Frigidaire’s energy efficiency, you want to compare our test results in addition to the manufacturer specified power draw in order to determine how its power draw compares to that of other dehumidifiers in its class. The environment you’ll be dehumidifying isn’t always going to be at maximum humidity levels. It may be at 80% or even 60% relative humidity for much of the time you’re dehumidifying, in which case you’ll want to prioritize our test results. Maybe you have a very severe humidity problem in which the environment is perpetually near 100% relative humidity, in which case you’ll want to prioritize manufacturer specified power draw.

Again, the FFAD7033R1 was measured to draw 632 watts of power at 50% RH and should draw as much as 745 watts of power at 100% RH. Data for the FAD704DWD is exactly the same.

While the measured power draw of 632 watts is higher than average for the size class (the average is 615 watts), the unit’s specified power draw of 745 watts is right around the average (the average is 744 watts). Additionally, and more importantly, the FFAD7033R1 has a well above average moisture removal rate. The FAD704DWD does not. Thus, despite the fact that both the FFAD7033R1 and the FAD704DWD have exactly the same measured power draw and manufactured power draw, the FFAD7033R1 is the more energy efficient dehumidifier. In comparing the FFAD7033R1′s performance to other 70 pint dehumidifiers we tested, it is also one of the most energy efficient 70 pint dehumidifiers overall.

Noise Output

Going into our noise output testing we expected the first major difference between the FFAD7033R1 and the previous model (FAD704DWD) to be in how much noise each unit produces. While we didn’t expect the newer model’s fans or compressor to necessarily be any less noisy, we still expected it to be the better option for those consumers looking for a low noise output dehumidifier. Why? This expectation was based on the fact that the new model intakes air through the back of the dehumidifier and exhausts air through the side of the dehumidifier. The previous model (FAD704DWD) took in air through the front of the dehumidifier and exhausted air through the top of the dehumidifier.

What does this mean for you as a consumer? The FFAD7033R1 taking air in through the back of the dehumidifier means that if you place the dehumidifier close to the wall in any particular room the fan will be pulling air towards the wall and not towards the center of the room where you or your family members might be located. This results in less audible noise being produced in the room. Additionally, the exhaust is on the side of the unit which means that you can orient the dehumidifier to exhaust in a certain direction. The FAD704DWD exhausts through the top of the unit which makes it much more difficult to control noise caused by the unit’s exhaust. You cannot “orient” it to direct noise in a particular direction. For these reasons alone, the FFAD7033R1 is already the much better choice if you’re looking for a more quiet dehumidifier.

Considering the information above, our noise output test results were far from surprising. The FFAD7033R1 garnered above average test results in all four of our noise output tests. It also outperformed the FAD704DWD in each test. At close range (in which the sound meter was positioned right above the dehumidifier’s control panel) the FFAD7033R1 was measured to produce 61.2 dB of noise on high fan speed and 57.2 dB of noise on low fan speed. Compare these results to the high fan speed close range average for the category of 67.2 dB and the low fan speed close range average for the category of 63.4 dB – the category being the 70 pint size class (the average of the sixteen different 70 pint dehumidifiers we tested).

At long range (in which the sound meter was positioned 10 feet away from the dehumidifier) the FFAD7033R1 was measured to produce 52.9 dB of noise on high fan speed and 48.8 dB of noise on low fan speed. Compare these results to the high fan speed long range average for the category of 53.5 dB and the low fan speed long range average for the category of 50.3 dB. The FFAD7033R1 is a great choice if you’re looking for a quiet 70 pint dehumidifier.

Moisture Removal

While the changes in design we discussed above (side exhaust vs top exhaust and back intake vs front intake) are good for noise output they do make moisture removal more challenging. Again, the previous model FAD704DWD pulls in air through the front of the unit which means that if you have it located close to the wall it will pull in air from the center of the room. The FFAD7033R1 pulls in air from the back of the unit which means that if you have it close to the wall it will pull in air between itself and the wall, which is obviously much less optimal for efficient moisture removal in any particular room. To maximize moisture removal efficiency we suggest that you either place the FFAD7033R1 in the center of the room (for severe humidity problems) or orient it so that the front of the unit is towards the wall and the back of the unit is facing the center of the room.

Additionally, the older model exhausts through the top of the unit which is more optimal for dispersion of dehumidified air. The newer model FFAD7033R1 exhausts through the side of the unit which, depending on the unit’s location in the room, may result in less even distribution of dehumidified air. Again, how well the FFAD7033R1 dehumidifies will largely depend on its orientation in the room you’re dehumidifying. Trying to orient the exhaust so that it directs outgoing air more towards the center of the room, vs directing the air towards a corner of the room.

From the discussion above, you might be inclined to think that the FFAD7033R1 didn’t perform as well in our moisture removal tests. Let’s see what happened.

The FFAD7033R1 placed second (out of sixteen 70 pint dehumidifiers we tested) in our 90% to 40% test and first (again out of sixteen) in our 80% to 50% test. It dehumidified our 50 sq ft test environment from 90% relative humidity down to 40% RH in under 10 minutes, accomplishing the feat in 9 minutes, 41 seconds. Only the Honeywell DH70W did so faster (9 minutes, 21 seconds). Compare this result to the 12 minutes, 14 seconds it took the FAD704DWD (which placed 10th) in the same test.

The FFAD7033R1 dehumidified the same room from 80% RH down to 50% RH in 4 minutes, 41 seconds. Compare this result to the 6 minutes, 27 seconds it took the FAD704DWD.

Clearly, based on our hands on testing, the FFAD7033R1 removes moisture more quickly and more efficiently than the FAD704DWD by a considerable margin (more than 20% faster). It also removes moisture more quickly than thirteen other 70 pint dehumidifiers we tested. If moisture removal rate is important to you (if you’re trying to dehumidify as quickly as possible) then the FFAD7033R1 is again an excellent choice. Not only does its high moisture removal rate result in faster dehumidification, but it also results in lower electricity costs. Because this dehumidifier will dehumidify any particular space faster than almost any comparable dehumidifier, it won’t need to run as long. And because it won’t need to run as long, it won’t draw power for as long. This reduced duration in power draw results in lower electricity costs.

Hygrometer Accuracy

Perhaps the most disappointing test results we obtained from testing the FFAD7033R1 were those results obtained from testing the dehumidifier’s hygrometer accuracy. It was measured to read the ambient air’s humidity between 3 and 4% below the actual room humidity. Many of the 70 pint dehumidifiers we tested were measured to read room humidity to within 1 or 2%. What does this test result mean for you as the consumer?

Should you set the desired humidity level on the dehumidifier to 40% RH, it will cycle off after reaching 43 or 44% actual room humidity. If you set the desired humidity level to 35% RH, it will cycle off after reaching 38% to 39% RH. The truth is that most consumers (if not all consumers) will never require their dehumidifier to set the humidity in a room to an exact number. If you’re comfortable at 40% RH and set the dehumidifier to 40% RH while the room only reaches 44% RH, chances are you’ll never be able to notice the difference. In other words, you won’t really be able to feel the difference between 44% and 40% relative humidity.

Why then do we test hygrometer accuracy to begin with? We test hygrometer accuracy only because it indicates the quality of the built-in hygrometer which can be indicative of other internal parts used in manufacturing any particular dehumidifier. There may also be some consumers who value hygrometer accuracy and want to be sure that if they set their dehumidifier to 40% RH that the room will actually reach 40% RH.

Included Features, Functionality, Build Quality, Warranties, and Value

Durability (Build Quality)

General Impressions

The FFAD7033R1, out of the box, looked to be made of much higher quality materials than those used to manufacture the previously popular FAD704DWD. For one, the LED display is visibly much higher quality. The buttons on the control panel also feel like they’re of higher quality. The water collection bucket and the brace across the top of the bucket look to be made of sturdier higher quality materials. The mechanism that secures the bucket into place when placed inside of the main body of the dehumidifier is also of higher quality. Additionally, the handle on the water bucket is of higher quality.

A problem area (as far as durability is concerned) for a lot of dehumidifiers equipped with a top handle is, you guessed it, the top handle. Large capacity (70 pint) dehumidifiers, especially, are quite heavy. Most are at least 40 pounds with many weighing in at a weight upwards of 50 pounds. Lifting up such a large weight by a singular extendable handle can cause potential issues if the handle isn’t very high quality. Despite the fact that we tested the FAD704DWD last year, we ordered another one this year to directly compare it to the FFAD7033R1 side by side. One of the things we compared on both units was the top extendable handle. Even though it may appear to be a very small part of the dehumidifier’s overall design, assessing such a small part can give us greater insight into the overall quality and durability of the dehumidifier. That being said, there’s definitely a lot more play (side to side movement possible) in the previous model’s top handle compared to the latest iteration’s top handle. The handle on the FFAD7033R1 also feels much more sturdy and solidly constructed. This is only one example of how the FFAD7033R1 is built better than the FAD704DWD. Overall, we were very impressed with the FFAD7033R1′s superior build quality and the quality of the materials used in its manufacturing.

Consumer Reviews

During hands on testing we only have any particular dehumidifier in our possession for less than a month. During this time we run it extensively to perform various tests but we still don’t run it nearly as much as the average consumer does during the course of even the first few weeks of ownership. For this reason we use consumer reviews as an additional tool in assessing how durable any particular dehumidifier is. We can physically inspect the dehumidifier and comment on the quality of its parts and workmanship but, just like you, we have to rely mostly on consumer reviews to find out just how durable any particular dehumidifier is over the course of several months of use. Of course, many consumers post a review when they first get the dehumidifier. Most, however, leave a review at least after a few months of use. We use these reviews as a guide to help us better understand how durable and reliable any particular dehumidifier is.

With that being said, at the time of the first writing of this editorial review, the FFAD7033R1 has received over 250 consumer reviews with an exceptionally low negative review rate (% of reviews that are 1 or 2 star) of only 5%. This is the lowest negative review rate of all of the 70 pint dehumidifiers we’ve tested. The FAD704DWD stands at a negative review rate of 11% while the average negative review rate for the 70 pint size class is 19%. With such a low percentage of negative reviews it’s only reasonable for us to conclude that the FFAD7033R1 is one of the more durable and reliable dehumidifiers on the market.

Overall Category Score

Over 250 consumer reviews, the large majority of which are positive, indicate that the FFAD7033R1 is both a durable and a reliable option in the 70 pint dehumidifier size class. Our own observations confirm that the FFAD7033R1 should prove to be one of the most durable and reliable 70 pint dehumidifiers that the market has seen thus far. It earns a perfect 5/5 for durability.

2019 Update: Several years have passed since we first assessed consumer reviews for this model. And while this unit’s negative review rate has increased slightly (it’s now up to approx. 10%), it is still well below the average rate for units in this size class (approx. 20%). We continue to score this model 5/5 in the category mostly because we still feel very strongly about our own impressions of the unit’s build quality. Comparing it side by side with all the other 70 pint dehumidifiers we tested, this Frigidaire unit was clearly composed of higher quality parts and materials and was, by far, the most well built.


The FFAD7033R1 has many of the same features that the FAD704DWD came equipped with. Like the FAD704DWD, it also features a humidistat that can be adjusted in 5% increments, a timer that can be adjusted in half hour increments up to 10 hours and 1 hour increments up to 24 hours, and a continuous mode. Like its predecessor it lacks an auto mode. We do note here that the FFAD7033R1 features three fan speeds (high, medium, and low) while the FAD704DWD only features two fan speeds.

Overall Category Score

The FFAD7033R1 has standard humidistat adjustability, slightly above average timer adjustability, and an above average number of fan speeds (most of the 70 pint units we’ve tested only have two fan speeds). It features a continuous mode but not an auto mode. We dock a point for its lack of an auto mode but it immediately gains a half point back with its inclusion of a third fan speed. The Frigidaire earns an almost perfect 4.5/5 for adjustability.


Set Humidity Range

The Frigidaire FFAD7033R1 is a 70 pint dehumidifier with effortless humidity control – it can be set to a desired humidity level as low as 35% and as high as 85%, which is exactly the range of the previous model, the FAD704DWD. This is also a fairly standard range for most other 70 pint dehumidifiers we’ve tested. There are models available that can dehumidify down to as little as 30% RH but like we discussed in the section on this unit’s hygrometer accuracy above, you’ll be hard pressed to feel the difference between 30% and 35%. 35% is already quite dry by most standards.

Operating Temperature Range

The FFAD7033R1, similarly to its predecessor and most other dehumidifiers in the 70 pint size class, can be operated in temperatures as low as 41° F and as high as 90° F. Note that these are only manufacturer guidelines. In other words, this is the temperature range in which the dehumidifier will work most efficiently. While the lower end of the range is fairly concrete (we don’t suggest you run this dehumidifier in temperatures below 41° F), the upper end of the range is more flexible. You’ll still be able to run this unit in temperatures greater than 90° F. You should be aware, however, that it won’t be as efficient at 90°+ F as it will be around 80° F or 70° F.

Gravity Drainage

One major difference between the FFAD7033R1 and the FAD704DWD is the fact that the newer model now features drainage coming out of the side of the dehumidifier. The previous model drained out of the back of the dehumidifier. The newer model also requires that you install an additional included drainage adapter onto the drain outlet before connecting a garden hose to use gravity drainage. The previous model only required you to remove the drain cap on the back of the dehumidifier before connecting a garden hose.

We’re not the biggest fans of these changes but we understand that gravity drainage on the new model can still work and can still work efficiently. For one, unlike the adapter on the Keystone KSTAD70B that has to be connected using two included screws, the adapter on the Frigidaire is threaded so that you can easily connect it by hand without needing to use any tools or extra accessories. Secondly, while we personally prefer to have drainage coming out of the back of the dehumidifier, this is nothing more than personal preference. You may like the fact that the unit drains out of its side and/or it may be more convenient for your particular setup.


Built-in Pump

The FFAD7033R1 does not come equipped with a built-in pump. You will need to buy a condensate pump and pump hosing separately if you need to drain the dehumidifier to a location far away or above it.

Overall Category Score

The FFAD7033R1 earns an above average 4.5 for versatility. Its set humidity range and operating temperature range is average to above average for its size class and while an extra adapter is required for gravity drainage, its threaded for easy installation.

Extra Features

Again, the FFAD7033R1 has many of the same extra features (or lack of extra features in this case) as the FAD704DWD. It doesn’t measure or show ambient temperature and more notably, it doesn’t have a warning LED that illuminates when defrost mode is activated. It does, however, come equipped with a check filter light. Note that the FFAD7033R1 does have a defrost mode that activates automatically when the dehumidifier senses frost build up on its evaporator coils. There simply isn’t a warning light that illuminates to let you know when and for how long it stays activated.

Overall Category Score

The FFAD7033R1′s lack of extra features earns it a below average 3/5 in the category.

Ease of Use

LED Display Clarity

We discuss this unit’s LED display clarity and compare it to that of other models in the size class in the section on this unit’s aesthetics later in the review.

Setup Difficulty

As was true for the FAD704DWD, setup is a breeze on the FFAD7033R1. Settings and features are clearly marked with no ambiguous buttons or warning lights. On many other 70 pint dehumidifiers we’ve tested you’ll definitely want to read the dehumidifier’s manual before trying to operate it. This is not the case with the FFAD7033R1. All settings/functions are easily accessed and inputted without issue.

Filter Removal Difficulty

The FFAD7033R1′s air filter is easily removed as the filter is easily accessed on the back of the unit (the FAD704DWD features a bottom slide out filter on the front of the unit that requires you to remove the water tank before removing the air filter).

Manual Clarity

This unit’s manual is very clear and well organized. Although the dehumidifier is generally easy to use and operate, you’ll find detailed descriptions and diagrams throughout the manual for more “advanced” setups such as setting up gravity drainage for example.

Water Tank Size

The FFAD7033R1 does feature a smaller condensate collection bucket (water tank) than its predecessor. The FAD704DWD features a 16.3 pint bucket. The FFAD7033R1 only has a 13.1 pint bucket. This approximately 20% reduction in water tank size means that you’ll be emptying the unit’s water tank 20% more frequently than you had to on the previous model. Of course, if you’re draining the unit via its external drain then this change is of no concern to you, but if you’re like most consumers you’ll be emptying the unit’s water tank every few hours. A smaller water tank means you’ll be emptying and replacing it more frequently. This is a definite negative for the FFAD7033R1 – perhaps its greatest negative overall.


Overall Category Score

The FFAD7033R1 is very easy to use but it’s less efficient to use because of its smaller water tank. Despite it being the only real negative in the category, it’s a big one, and for its smaller water tank alone we have to give the FFAD7033R1 only an average 3.5/5 for ease of use.


What immediately struck us when first taking the FFAD7033R1 out of its box, was the fact that it was a surprisingly modern looking appliance. Almost all of the 70 pint dehumidifiers we’ve tested thus far (with only a one or two exceptions) look as if they could have been manufactured in the 1990s or even the 1980s. The plastics on these units have a beige color very reminiscent of the type of plastic you might have seen on appliances manufactured in decades preceding the 2000s. While most types of appliances (vacuums, steam irons, etc.) have seen a more modern approach to their design over the last few years, the same cannot be said for dehumidifiers. The FFAD7033R1 breaks this mold with a much more modern design than what we’re used seeing in a dehumidifier.

The plastics used on the FFAD7033R1 all have a clean white color with a glossy finish, unlike the beige matte finish on the previous model, the FAD704DWD. The control panel has a much more modern feel and design and the dehumidifier is even equipped with a very modern looking blue LED on the front panel that flashes when the water collection bucket is removed or not replaced correctly.



We rated the FAD704DWD as one of the most portable 70 pint dehumidifiers on the market in 2014. This was primarily because it featured side pocket handles and a top extendable handle. It also featured outstanding cord storage. The FFAD7033R1 again features a top extendable handle and excellent cord storage. However, it does not come equipped with side pocket handles, which is disappointing for a several reasons. If after years of use the top extendable handle on the dehumidifier does break, side pocket handles prove invaluable. Additionally, it’s more comfortable to pick up a dehumidifier by its side handles (vs picking it up by the top extended handle) for some consumers.

That being said, as we cover in the durability section earlier in this review, the top handle on this dehumidifier is much better quality than the one equipped on the previous model. It is such a high quality that we really cannot imagine a scenario in which it will ever break, outside of extreme abuse. The fact that some consumers prefer picking up a dehumidifier by its side pocket handles still remains. But the fact that the handle that is included (the top handle) is highly durable makes our first concern -that you might need side pocket handles in case the top handle breaks – a moot point.

Overall Category Score

The FFAD7033R1 weighs 47 pounds which is only 1 pound more than the FAD704DWD (46 pounds) but 7 pounds more than the very light and portable Keystone KSTAD70B which weighs only 40 pounds. If you’re looking for a portable dehumidifier the FFAD7033R1 is certainly not a bad choice, with its very sturdy top extendable handle and excellent cord storage, but there are better choices out there. That being said, those better choices are only better choices if portability is of utmost concern to you, in which case we’d probably recommend a smaller dehumidifier (that’s lighter) anyway. All in all the Frigidaire earns a respectable 3.5/5 for portability.

Warranty (Manufacturer’s)

The FFAD7033R1 comes with the same full 1 year warranty that comes with the FAD704DWD. Like its predecessor, it also comes with a 2 to 5 year warranty on the sealed system of the dehumidifier (the compressor, condenser, etc.). This type of warranty is standard for the 70 pint size class although there are exceptions. If you’re looking for a dehumidifier with a better warranty you only have two choices – the Danby DDR70A2GP and the ArcticAire ADR70A2G, which both come with a full 2 year warranty (vs the 1 year on the Frigidaire).


At the time of this review the FFAD7033R1 is retailing for about $270 while the FAD704DWD is priced about the same, also at around $270. The average price of all sixteen 70 pint dehumidifiers we’ve tested is $254. In evaluating the FFAD7033R1′s value we have to consider what it is and what it offers, and how these things compare to other 70 pint dehumidifiers on the market. We do so in the final thoughts section below.

Final Thoughts

In trying to determine whether the FFAD7033R1 is worth its approximately $270 price tag we said that we have to consider what it is and what it offers and then compare those things to the competition.

So, what is the FFAD7033R1 and what does it offer? The FFAD7033R1 is, first and foremost, a dehumidifier. You’re buying this appliance to dehumidify a home or a place or business. The FFAD7033R1 is, simply put, a much better dehumidifier than most other 70 pint dehumidifiers we tested. That is to say, it dehumidifies faster and more efficiently than most other units we tested. It was the second fastest in dehumidifying our test environment from 90% relative humidity down to 40% RH and the fastest (out of the sixteen 70 pint units we tested) in dehumidifying the same space from 80% RH down to 50% RH. Keep in mind that because it removes the same amount of moisture faster than a comparable dehumidifier it will also use less electricity than any comparable dehumidifier because it will need to run for a shorter duration of time. Definitely take this into account as you consider its price tag. The cost of a dehumidifier doesn’t end when you pay the purchase price of 200 plus dollars. These are heavy duty power hungry appliances and in most cases in which they’re needed they’re going to be running for long periods of time which results in substantial energy costs. The FFAD7033R1 is not only going to remove moisture faster, but it’s also going to do so more efficiently than every other 70 pint dehumidifier we’ve tested.

Secondly, the FFAD7033R1 is quiet. It rated above average in all of our noise output tests. Its design also lends itself to being a good option if noise output is important to you (we discuss this in greater detail in the respective section on noise output near the beginning of the review).

Thirdly, the FFAD7033R1 is a very durable and reliable dehumidifier as we discuss in the respective section on durability earlier in the review. This quality once again ties into value. Yes, the FFAD7033R1 is slightly more expensive than many other comparable 70 pint dehumidifiers, but consider the fact that that extra $20, $30 of savings can turn into a $200+ loss if the less expensive dehumidifier breaks outside its warranty period. That is not to say that the FFAD7033R1 is impervious to breaking down while other dehumidifiers are not. All that we’re saying is that you definitely want to take into account that consumer reviews and our own observations indicate that it’s more durable than most other 70 pint dehumidifiers on the market.

With all of the positive things that we’ve had to say about the FFAD7033R1 you might be inclined to think that we’ve been paid to endorse Frigidaire’s products. Rest assured, this is not the case. We bought this dehumidifier and every other dehumidifier we’ve tested from the same retail stores you’ll be buying your dehumidifier from. We simply feel very strongly about the quality of this dehumidifier. We’ve tested a lot of dehumidifiers over the last few years and we’ve seen a lot of dehumidifiers that have been cheaply built and unintelligently designed. Despite these issues these dehumidifiers still retail for upwards of at least $200. The Frigidaire is a breath of fresh air. At around $270 it really is a substantial upgrade over its predecessor and a much better dehumidifier than any other 70 pint dehumidifier retailing for mostly under $270. We can say without hesitation that it’s the best dehumidifier we’ve tested thus far. The FFAD7033R1 receives our highest recommendation as the best buy in the 70 pint size class in 2020.

      The FFAD model is the newer equivalent to the FAD model. Though both models have now been replaced by the latest model – the FFAD5033W1.

    • Anonymous says

      I would never buy one! We had one that broke after a year and a half which was replaced by Frigidaire. The replacement we received only lasted a year and Frigidaire said it would be replaced and sent us the form which we submitted. Never got a replacement. It impossible to get through to customer service via phone and our emails went unanswered. Bad company to deal with and bad product.

  1. Victoria lemieux says

    Do you have a review for the FGAC7044U1 model? Is it comparable or which fridgidaire model is currently the best for the 70 Pint in 2020? Or is there another brand I should be looking at? Thanks so much!

    • Admin says

      The newest high capacity Frigidaires are the FFAD5033W1 and FGAC5044W1. These two units are equivalent except that the FGAC5044W1 can be controlled remotely via an app. For most applications I recommend the non-wifi model, the FFAD5033W1.

  2. Len says

    I have the Frigidaire Dehumidifier FFAD7033R1. I contacted Frigidaire and they confirmed the plastic cover on the bucket is not removable. Any suggestions on how to clean the mold developing in bucket given I can’t access the inside to scrub or wipe down? Frigidaire did not have any suggestions. Not sure if this is a common issue. Thanks.

    • Anonymous says

      I use a 1/4 cup of sodium percarbonate in the bucket every so often. Sodium percoarbonate is the active ingredient in Oxyclean and it produces hydrogen peroxide when it mixes with water. It kills bacteria and mold on the bucket walls, no scrubbing required. I still have slime left under the top plate, though; at some point I will submerse the bucket completely in my utility sink and leave it to sit overnight with a 1/2 cup of sodium percarbonate. ‘hope this helps.

    • Anonymous says

      It is removable. I’ve removed mine several times for cleaning. You need to be careful not to break the side pieces holding the handle which then allows you to remove the cover.

    • Danny says

      The plastic cover is removable…turn the handle to a certain angle and pull back on the tab holding the handle in place. Unclip the tabs holding the cover in place and the cover lifts off easily!

  3. Mary Carter says

    I have tried buying the Frigidaire FFAD5033W1 dehumidifier, but cannot find it. Home Depot is completely out. I have also tried on Amazon, but can’t find the model #. Where can I buy it? Can you buy directly from Frigidaire? Thank you.

    • Admin says

      It should be back in stock at major retailers shortly. This time of year popular units like the FFAD5033W1 tend to go out of and then back in stock quite frequently.

  4. Francis says

    Frigidaire FAD704DWD

    Just got me one and a noticeable thump sound is made about every 12 mins from the compressor I guess. Is this normal or a defect? I have consulted Frigidaire and the answer is: normal! The unit runs “quiet” except for this thump sound…….. Also, when I set the sensor to 45 or higher it cycles off after about 7 (seven) mins and cycles back on after 1 (one) min or less. Defective or normal? The unit has been running for about two weeks. Initially in CO mode for about two days, then set to desired humidity levels……..

    This is my first dehumidifier. I ask the question about the cycle on/off frequency, because I am comparing it to a heater unit which brings the temperature to the setting and shuts off, but does NOT cycle back on so rapidly.

  5. Roy Myers says

    I live in an airpark in Florida. My hangar is 32 feet deep and 43 feet wide with a ceiling height of 14 ft. I want to keep my toys ( airplane, boat, classic Mustang ) dry as well as my tools. I thought about airconditoning but I open the hangar door several times a week and don’t normally work in the closed hangar in the heat of the day. Humidity is our biggest problem down here and makes a 90* day pretty wet, gooey and miserable. What make/model of dehumidifier would you recommend in my case. Thanks in advance.

  6. Eric says

    Does the frigidaire fad504dwd19 have an automatic defrost mode? I can not seem to find the information anywhere. Thank you

  7. Randy Elling says

    I keep getting an FO fault on my FFAD7033R1, I pull the plug and wait 5 minutes and plug baFO fault returns. What should I do next the unit was purchased just over 1 year ago.

    • Anonymous says

      Mine does the same thing and Frigidaire won’t answer the phone or return my emails.This will be my LAST Frigidaire product!

      • Dan says

        I’m having the exact same problem – F0 error code and no response from Frigidaire. I am considerate of poorer response during this time, but my basement is very musty!

    • Tom says

      Mine worked fantastic the first year. I haven’t changed a thing and this year it runs for a few minutes then it shuts off and displays FO. What’s changed???

    • Lou says

      I also keep getting the F0 error on my FFAD7033R1 after only 2.4 seasons of use and trying to put it back into service after the winter. I used it well within operating temps & kept the filter clean. I had been using the hose drain, but to troubleshoot and see if it was getting any water I used the bucket & only got a few drips and some rust. When taking off the air filter & using a flashlight you can see the coils have rusted on the right side. Lots of posts about the F0 code on amazon and walmart.

      • Linda says

        I finally reached Frigidaire. The F0 is a hardware fault and the unit will NOT run any further. They sent me a different model as a replacement unit. My unit is the same age as in the other comments, about one year old.
        Do NOT buy this unit! From what I deduce, there is a design flaw that WILL cause this unit to fail.
        Try calling later in the day to reach them.

  8. Ed says

    The FFAD7033 appears to be discontinued. No longer available on major sites, including amazon, where it’s only available from third party sellers at exorbitant prices. Also, no loner on Frigidaire’s website.

  9. Catherine Brown Dougherty says

    I’m buying a new dehumidifier to save money on electricity. After reading your review, I wonder if setting the fan speed at low might not be a cost savings. Because, if it can dehumidify faster Maybe it’s less expensive because the compressor shuts off quicker. Would you kindly suggest a fan setting for regular days when it’s not that wet?

    • Admin says

      We recommend always running the unit on high fan speed. Power draw for the fan is negligible compared to the compressor, etc.

  10. Michael Weber says

    I live in a very damp house in upstate New York. In winter I had severe condensation problems at windows and skylights. For a long time, I thought the skylights were leaking from the amount of water dripping off the casings. When I realized that the problem was condensation, I purchased two of the model FAD704DWDE dehumidifiers. I have used them for the past three years (now in their fourth year of use) and they have solved the condensation problem in my house and they work beautifully. I have placed one on the first floor and one on the second floor of my small house. They are only used in winter when the windows are closed tight. My only complaint is that they are a bit on the noisy side. My question is do you think the model FFAD7033R1 is so much quieter than the FAD704DWDE that it would be worth replacing one or both with the newer FFAD7033R1?

  11. Mark says

    I live in Lakewood, CO (a suburb of Denver) in a ranch home. I rent my basement unit, as a full apartment, and invested notable funds into a very nice kitchen for the apartment unit. Colorado is generally a low humidity state. However, I know that humidity levels in the basement apartment are higher (from moisture encroachment from soils [the basement apt. is completely below grade]. The basement moisture levels are not ‘high’ by most standards – I bought a hygrometer, and they generally range, for example, from 25% to 40%, although I have seem them approach 50% (not common.) My question is whether purchase of a basement dehumidier is needed – I want the space to be comfortable, but if 25% to 40% humidity is normal and considered comfortable, there’s likely no need. Part of the latter question is whether there is a ‘bottom’ humidity limit to which a dehumidifer will bring moisture levels (e.g. if a dehumidifer will only bring them down to 35%, no logic in purchasing one); further, if insufficient moisture itself can become an issue. Its just that at some times, I assume that a quality dehumidier would maximize comfort of the apartment vs. a sometimes ‘cool’ basement feeling Can you please give some input/feedback? Thank you very much!

    • Admin says

      Comfort is highly subjective. We do go into detail quite a bit regarding when a dehumidifier is absolutely necessary in our guide for buying a basement dehumidifier. It may give you better insight into whether you need a dehumidifier or not.

      You cannot set the desired humidity level below 30% RH on most models on the market.

  12. Jau says

    First, thank you for leaving a such a great review. I have 950 sq ft one bed room apartment with one bathroom. And, I see why you are recommending 70pint size dehumidifier if I can afford to pay. However, I think 70pin size seems too much for my apartment but if I can afford do you still recommend me getting 70 pint?

    And, if I leave the dehumidifier in the living room will I get same or precise humidity throughout my apartment? Under an assumption that I’ll leaving all doors open.

    • Admin says

      We definitely recommend a full size 70 pint unit for an approx. 1,000 sq. ft. space like your apartment.

      And yes, the dehumidifier will be able to lower the humidity in the whole apartment – even in separate rooms and even if it’s not placed in those rooms.

  13. Jeanette Cousino says

    I am using s power strip/surge protector because a previous humidifier was damaged when we had a power surge.
    I am concerned at the recommendation not to use an extension cord’s impact on this option.

  14. Peter says

    Great review. I have an 1,130 sq. foot finished basement. Currently the humidity stays between 60% and 63%. I am looking to keep it around 40%. My interest is the new Frigidaire
    models. What do you think would be the best solution for me. 30,50 or 70 pint.

    Thank you

  15. Amy says

    How much does the tank weigh when full? To be able to lift and carry it to a sink to dump- I might like the smaller size.

  16. Richard Kearns says

    Does the FFAD7033R1 automatically restart after it experiences a power outage? How does this work?

    • Admin says

      Yes, it does. The unit will turn back on with the exact same fan speed, humidity setting, etc. it was set to before the power outage.

  17. Ruud says

    Thanks guys for the detailed review!

    I am a first buyer and consider the FFAD7033R1.
    I did notice in the review is mentioned no auto function is available.

    Maybe a strange question, however can I run this product continuously by setting it to eg 50% humidity level and letting it do it’s purpose?

    So if the humidity exceeds 50% it starts automatically again to get back to the set level? And accordingly pause when the set level is met? Keeping it connected?

    Living in Dubai, where I will need it continuously to function across the summer (several months). Ideally without me every morning/ evening touching it again.

    Thanks for your clarification!

    • Admin says

      Yes, the unit will essentially run completely automatically when you set it to a desired humidity level. For example, if you set it to 50% RH (relative humidity) it will run as long as the RH in the room is higher than 50%. Once the RH is 50% it will automatically shut off. It will automatically turn on again when room RH goes back above 50%.

  18. Jessica says

    I’m confused by your review… Where is the best location in a basement to get the best results… With the back facing a wall or in the center of the room?

    • Admin says

      The center of the room if possible. Otherwise, the unit is still very effective near a wall. Just make sure there’s at least one foot of clearance between the wall and dehumidifier.

  19. cryptic coptic says

    Can you override the filter feature from shutting the unit off? I may be gone for a month or two in the winter and need it to keep running to prevent mold. In a previous dehumidifier, after 4 filter cycles it still had no material in it.

    • Admin says

      The check filter light is only a warning light. It will not prevent the unit from running when it’s activated.

  20. Myles McDonald says

    I have a FAD504DUDM dehumidifier. My question is: If the unit reaches its desired hunidity level and shut down, will the unit automatically restart if the humidity level increases. I want to set the unit at say 60%, leave it running on low speed, for about 4 months. People will check on the unit while I am not there.

    thanks for the help.

  21. Ed says

    Thanks for your very comprehensive comparison of the Frigidaire 7033 vs. the 704. Regarding noise of operation. You specified the dB figures for the 7033 but not the 704. What are they? Also, if I position the 7033 so that the back vent faces forward, would that not result in greater noise (per your comment about drawing air toward the wall would be quieter than toward the front)? If so, would not the 7033 and the 704 be comparable in noise? Thanks!

    • Admin says

      Comparing raw dB numbers is not nearly as helpful as comparing the actual design of each unit for this particular comparison (raw dB numbers are very similar for both units accounting for their difference in design and the limitations of our testing). The vast majority of noise is generated by the exhaust of the dehumidifier. This noise is distributed upwards and throughout the room with the 704 while it can be directed completely away from you with the 7033. This is the biggest reason why the 7033 is the superior option if noise output is a concern for you.

      If you were to rotate the 7033 so that the intake vent faces the room like the 704 then the 7033 can still be quieter because the exhaust can be pointed away from you and, again, it’s the exhaust that generates most of the noise.

  22. Evelyn says

    I recently purchased the FFAD7033R1 70 Pint and initially was very happy with it. I had a drain hose connected to it preventing the task of emptying it. In your review, you mentioned that it lacked an auto mode. Are you supposed to be able to set this unit up to operate for 10 or 24 hours at a time? How inconvenient to have to constant remember to turn it on during a summer humidity period! My issue with this unit was that would only run in continuous mode. It would never, ever shut off even after reaching the set 40% humidity. It ran non-stop for a week until I shut because the unit felt warm to the touch. I had no luck when I called Frigidaire for help. I returned the unit. Isn’t there a unit that will shut off once the set humidity is reached?

    • Admin says

      You definitely had a defective unit. It should shut off automatically after reaching the desired set humidity.

  23. Rob says

    I have a 909 sq ft or so place…would it be overkill buying a 50 pint or bigger as you don’t recommend buying a 30 pint?

    Avg humidity is at 67. I need the humidity level to stay in the 45-55% range.

    Thanks for all of this!

  24. Sara Norrman says

    Hello! Thank you for your super informative site!
    I am looking at purchasing the recommended Frigidaire FFAD7033R1 for our basement. We do not have a floor level drain and instead of pumping I am considering putting it on a table or shelf so it can drain into our slop sink (next to the washer). Do you have any recommendation re: how much weight I should plan for? Ex. I think a shelf rated for 50 pounds would be too little considering the unit itself is almost 50lbs.
    And can you please also confirm that adding a hose is really easy?

    • Admin says

      We recommend not using a shelf unless it’s a very wide shelf. The last thing you want is for the dehumidifier to accidentally fall of the shelving. We recommend a surface that can hold at least 100 lb. (again, just to be safe). And yes, it’s very easy to connect a hose to this unit for gravity drainage.

  25. Alex says

    Great review but, the use of power is measured by hour? Month? Year?
    Its important to specify something like time if you are doing a review. Thank you

  26. dave says

    Can you say more about the timer and how it functions. If I purchase an external pump, can I set the timer to run during the day and off at night when I travel for a week and am away.

  27. EBerns says

    I am draining about twenty feet with about a 2 foot height differential between drain spout and floor drain. If this distance and height is not enough to drain condensate, will water fill bucket and shut off unit? Thank you for this excellent reference site and its ease of use.

  28. Bee says

    I’m replacing the Frigidaire FAD704DUD due to a recent problem + I found out about the recall. Good unit. Have used it in my approx. 1,200+ sf slab basement (not a living space) in the southeast on continuous mode for about 6 years. No problem until recently – stopped running continuously, now filling up bucket instead. Think there is a clog close to the hose connection in the machine. Anyway, which would be the best choice for a continuous drain dehumidifier in a non-living space basement? Maximum, quick moisture removal is my main concern. I know the dehumidifier I have been using is only for 1,000 sf max space, but I don’t want to spend more, so looking for a dehumidifier with similar specs. Will only be using in continuous drain mode, which drains into a sump pump. Must have auto shutoff if CO quits working & the bucket fills up, & must come back on automatically if the power goes out. This dehumidifier will not be monitored on a daily basis – more like weekly. Thank you!

  29. Bill B says

    Where are the “F0″ warnings here? The unit is fantastic for about one year when many fail and quit working. I loved how quiet it was, how it quickly removed humidity and how it was able to move air but am very frustrated when it quit working after one year. Frustrating to have such a great unit with a design flaw causing “F0″ failures.

    • Admin says

      At this time we believe it’s simply out of stock. We will keep the page updated if it has in fact been discontinued.

    FFAD7033R1 is still out of stock. Any insight on it being no longer produced and replaced with a new model? I currently have a Friedrich 70BPA and its uses over 25% of my total electric use for the year. My basement is 1300 sqft, wide open, and not extremely wet. I have setup an external condensation pump and I recommend that solution to anyone that needs a pump. The 70BPA pump failed after 2 years. If there is a new model coming I will wait if not what is your recommendation?

  33. Marie says

    You sold me on this unit… until I went to buy it and saw there was the California Proposition 65 cancer warning on it. You should post that at the top of your page before people invest a lot of time reading your whole review. Also, should that not be factored in to your ranking? I’m buying a dehumidifier to make my home environment healthier… I’m not going to intentionally bring cancer causing chemicals into my house.

    • Chris says

      I want to drop the humidity in my home which currently sits at 40-45% (basement / first and 2nd floors) in order to eliminate window condensation during winter cold spells. Total house SF is 3200 and basement is another 1300sf. I know I’m kinda pushing the envelope with this “cheap fix” however:

      If I put this model in my basement will it help the whole house at all or is it a fruitless endeavor? Is the best bet to just move this thing around the floors or the home? I feel if I can get the basement very low, then that would aid the air within the ducts by default which in turn wold help to reduce the RH on 1st/2nd floors….what are your thoughts on this???

      I looked at a whole home dehumidifier but was floored by the price. Do you have any alternative suggestions how to get living portion of my house down to say 20-25%? I was surprised to see most 70pt only go down to 35%….
      Thanks and great reviews!

      • Admin says

        We recommend that you try placing the unit in different parts of your house to see how well it distributes dry air throughout your home. If you find a spot that works well just leave it in that spot. If you can’t find a spot that works we would recommend purchasing an additional unit.

  34. Andrew Beauchamp says

    i can spend around $200, so purchasing the newer frigidare 70 is not an option.
    I am in a 600sqft space.

    newer model frigidaire 50 for $200
    older model frigidaire 70 for $230

    I have read through your long review and cant decide if the advantages of the newer model outweigh the lower capacity. any advise?

  35. Mike V says

    Our basement is 20×50 and this unit will be in the wall at floor level through a cut out in the wall. So…the front of the unit will face into the room and the back goes into the closet where it drains into the sump well. Does this mean that the —4DWD unit is preferable over the new —33R1 because it draws from the front and not the back…? Trying to weigh out the other advantages of the —33R1 and giving them up so as to have the older unit that draws from the front.Thank you for this venue to ask questions.

    My wonderful Winix WDH871 70-pt dehumidifier just died after several years of perfect operation. It actually runs and pumps but keeps icing up, so I have to replace it. My question is, if I use an add-on condensate pump, do I place it inside the water receptacle? I don’t find that you have addressed this anywhere in your otherwise thorough and enlightening review.

  37. Mickey DeNicola says

    Also, alternatively, can I use an adapter? I know it says not to, but I wonder since this does not draw much power if it’s OK and that’s just an over-careful recommendation. Thanks again.

  38. Curt L says

    Thanks for the detailed analysis. Your skepticism about the various charts threw me as I’ve not bought a dehumidifier before and thought I had the numbers right. I’ve looked over your analysis carefully and am still wondering if the Frigiidaire unit you like is robust enough for the 1500 sq ft basement I am about to finish. My ACH is 3 . Am I OK with just the one unit or two I need two to meet CFM numbers? Thanks for any help you can give this newbie.

    • Admin says

      We recommend buying one unit and testing it out in the space. If you find you need one more you can always buy another later.

  40. Larry Kaye says

    Amazing site! Do you guys review any other products?
    Just want to point out one thing: Your review states ‘The newer model also requires that you install an additional included drainage adapter onto the drain outlet before connecting a garden hose to use gravity drainage. ‘ In my manual it says that the adapter is there to facilitate frequent connection/disconnection but the option to attach directly without using the adapter is always valid. I have not hooked it up yet (and can confirm the weakest point being the small tank size…..) so can’t say either way.

  41. Linda Barker says

    Can you tell me if the FFAD7033R1 model requires a special outlet other than a normal grounded three-prong plug? My boyfriend thinks he has to hire an electrician for them to wire a “time delay fuse or circuit breaker.” It’s only draining 6.7 amps. The warning on the tag that is attached to the plug says, “The circuit protection must be a time delay fuse or circuit breaker.”

    The owner’s manual says, “Your dehumididifer must be plugged directly into a properly grounded and polarized three-prong receptacle.”

    To me that sounds like I only need a grounded three-prong receptacle.

    Also I’d like to ask if it is better to plug in a surge protector into the outlet and the dehumidifier into the surge protector? He thinks it is safer from a power surge being on a surge protector.

    We had the older model,the FAD504DWD go bad on us and he thinks it fried because of an electrical surge. We had it about 3 years.

    Is see that the FFAD7033R1 has an auto defrost feature but the oler model FAD504DWD doen’t. Could that be the reason?

    Please reply soon before he wastes money paying an electrician to install a new outlet.

      • Mickey DeNicola says

        Can I use an appliance extension cord for this model? I have a few 3 prong outlets but most of them are not 3 prong. I am concerned about the correct outlet as my house is 200 years old. I do have updated electric service and a circuit board.

  42. Moxie says

    For model FFAD7033R1 (70-pint), what is the vertical distance between drain outlet and floor (bottom of caster wheels)? Unit will be positioned on floor next to a window with top of window sill positioned 9-inches above floor. For gravity drainage to work, the connector hose must pass over the window sill.

    Also, based on bedroom (with attached bath) dimensions of approximately 230 sq ft (or 2,000 cu ft), would the 50-pint size/capacity (Model: FFAD5033R1) be sufficient? Or smaller?

    We’re not having any issues with mold, mildew, or excessive moisture, just looking for a little extra relief from typical Alabama summer humidity!

    Thanks for providing this great resource. Looking forward to your reply!

    • Admin says

      The vertical distance between the drainage port and the floor is more than 9 inches (it’s closer to a ft.) so you will not be able to drain this unit (using gravity) out of the window you described.

      For our thoughts on which capacity unit to buy please see here.

  43. George STEEVES says

    I have a 1 bedroom condo, approx: 850sq ft. Would a 70 pint be an overkill for my condo & does Frigidaire make a 30 or 50 pint.

  44. George Araujo says

    Can you please tell me which one you would choose and why? Also I get different info of square ft of coverage on the units can you give correct info. FFAD7033R1 vs Keystone KSTAD70B

    • Admin says

      For complete recommendations, including a discussion of dehumidifier square footage, see our general buyer’s guide here.

  45. dr mac says

    How far can a hose reach between the FFAD3033R1 and a slightly down-hill drain? My 20-30 foot cellar floor is damp at one end (hydrostatic pressure in the middle of the flor), but the drain is at the other end… Can I run a garden hose down to the main drain?

    • Connor says

      I have a FAD704DWD that I have been using a 50 ft garden hose to a down hill drain, no problems. If hose is exposed to freezing temperatures, this would be a bad idea.

      • Admin says

        Yes, we would not recommend it although you could certainly test to see if the water at the end of the house actually freezes up.

  46. Rich G. says

    I need to replace a dehumidifier that no longer functions and am interested in the FFAD7033R1 that you reviewed so well. My only concern is the drain position which is at the side. Is it possible to drain, continuously through the back by attaching a hose (w/o adpater) and “modifying” the back cover?

  47. Steve B. says

    My last dehumidifier kept freezing up. I use it in our basement which is about 60 degrees in the summer. I want one with an auto defrost cycle. Your review of the Frigidare FAAD7033R1 says it has an auto defrost cycle. However, the Fridgidare web site, technical data and user manual do not mention it. I called Frigidare customer support but all they did was read to me the info on their web site. Can you please confirm that it has auto defrost? If it does, why is there no mention of it from Frigidare?

    • Admin says

      The user manual does mention it. In the last section of the manual it addresses several common problems and what the solutions are to those problems. One of the problems mentioned is frost building up on the unit’s evaporator coils. The solution states that the unit will defrost automatically if this happens. This is the unit’s auto-defrost functionality we are referring to.

  48. Debbie Long says

    I notice that you can out a water hose on the Friedrich 70 Pint Dehumidifier ,but,according to your review it is not as high rated as this one.Can you use a water hose to put on the drain of this one as well?

  49. Deborah Gentry says

    I have a 1.5 story house with attic space on both the front and back of the house. There is no insulation in the knee walls of the upstairs room, or in the floors of the attics. We have a “hot roof” with spray foam insulation encapsulating the entire building envelope, but the humidity is too high upstairs. We want to dehumidify both attics. Do we need two units (one for each attic), or would one unit suffice?

    • Admin says

      We recommend that you buy one unit to start and test it in the space to see if it’s sufficient. Only if it doesn’t sufficiently dehumidify the space do we recommend that you purchase a second unit.

  50. Heath H. says

    Hi, I am considering placing this dehumidifier in an insulated metal building that I just built. It is about 720 square feet. Would you recommend this dehumidifier for a building like that? Thanks.

  51. CHRISTIAN says

    Hello, i have a 200 sqf room where we placed a jacuzzi. Humidity is terrible, all walls are always wet. Is this enough or do you suggest another model. Thank you

  52. Gene Epstein says

    I already own several dehumidifiers since I have a large property with numerous buildings that have antique cars.I tried Haiers but they seemed to be junk.I purchased a 70 gal Frigidare 4DWD and it has been great with the water hose coming from the rear.I just want one more and like that the ‘filter’ is on the side for quick cleaning but concerned that it my water line exit hose has to go through a wall then I would need the older one with side hose exit.
    Confused..Does the newer version come with the fitting for side hose or does it have to be purchased separately?


  53. Curtis says

    I have a 1200 sq ft fully insulated metal shop and am having issues with high humidity during the change of seasons twice a year. I live in the south on the coast and would like to know if this dehumidifier will work for my application as we often have 90% plus humidity levels.

  54. Tina Faul says

    Hi! Thank you for all the great information. We have a 2 story home approx. 1800 sq ft. All bedrooms and one bath upstairs. We live in South East Texas, high humidity!!! Ugh! Condensation develops on our a/c vents during Spring and mostly Summer and the air feels damp. We have approx. 800 sq ft upstairs and approx. 1,000 downstairs. Would you buy two units, one for each floor? Thank you!

    • Admin says

      We would recommend you purchase one unit first and test whether it’s sufficient for your whole house. If you use the dehumidifier in combination with a central A/C system, one unit should be sufficient even for a two story home.

  55. Mike Moore says

    I have, what I think is mildew, musty smells originating out ot the effluent pump area in basement closet (possibly water seepage under the slab to “below slab level” pump). I’ve performed most of the diy test, and don’t think the smell is septic system related. The finish basement is appx 1200 sq ft. We’ve been in the house about 4 years, haven’t had a basement dehumidifier, but have thought I needed one. Do you think the use of this dehumidifier would be a good step in trying to deal with the smell issue. I may only be dealing with the “symptoms”, and will eventually need to have professional plumber investigate. I would be interested in your thoughts on this situation.mthanks

  56. Sarah M says

    I am looking for a dehumidifier for the lower level of a 1420 sq ft raised ranch. The one I have currently is rather noisy, and seems to put out quite a bit of heat, which is not wonderful during the summer. So I am looking for a newer dehumidifier that runs a bit more quietly, with a little less heat output, but don’t want to have to empty the bucket 7 times a day. I leave my current set at 60% humidity, and that seems to keep it fairly comfortable. Do you think the newest Frigidaire FFAD7033R1 would be my best bet? Or is there another you would recommend?

  57. Oana says

    Great reviews, any chance you would have any recommendations for Europe? Can’t buy this one as I can’t get it delivered in Ireland and I’m really stuck as I don’t know what to buy. Thanks

  58. mala says

    I noticed that the fan is running continuously even after the humidity reaches the set level. Is it normal? is there any setting to stop the fan after the humidity reaches the level

  59. Steve Wilson says

    If the power goes out while it’s in operation, when power is restored to the unit will it come back on automatically?

  60. Angela Dodds says

    I have read your decibel level review & now the review for the Frigidaire FFAD7033R1 & feel that this s the unit that would suit me best. I live in an RV & am looking to get another unit for the bedroom. The one in living room is just not strong enough to pull the air from 38′away. I don’t know the model, but the unit that came with is a GE 45pint. From the noise on start up, I am pretty sure that it has a compressor, you never mentioned one in any of your reviews. Does the FFAD7033R1 have one? It is my info that a dehumidifier performs better with a compressor. Thank-you for your reviews & time.

  61. Warren says

    Your reviews are excellent, and I wish I had seen it before I just purchased the Kenmore KM70 which does not show the ambient humidity level. I read your great review of these two Frigidaire models, and was about to return my Kenmore to purchase one of these, when I realized that you said that this model also does not show the ambient humidity. You write extensively about what a negative feature this is on the Kenmore model (with which I agree) but only one line about it in this Frigidaire review, which I almost missed. Am I missing something about why you did this? Please respond soon because I need to make a decision.
    Thank you very much for your extensive work.

    • Warren says

      Hi again,
      Just noticed that you wrote that the Frigidaire does not show the ambient temperature, but you did not write that it does not show the ambient humidity. So I assume that both Frigidaire models do show the humidity level, while the Kenmore does not. That would explain why you did not stress this factor on the Frigidaire review. Is that correct? Thank you!

        • Sam says

          Thank you for your extensive reviews. Very helpful! I am in the UK and am looking for the equivalent to the Frigidaire FFAD7033R1 70-Pint Dehumidifier with Effortless Humidity Control, White. Can you direct me ?

          Thanks very much

  62. Jennifer Duffy says

    Our basement is approximately 2000 sq ft. With half of it unfinished, containing 2 furnaces, 2 AC units, and water heater.
    The remaining half of the basement is finished, and made up of four rooms. Our sump pump is located in a closet inside of a guest bedroom in the finished basement. It smells quite musty in the basement overall, and especially in the guest bedroom. We already have a 50 pint dehumidifier running in the finished part of the basement, but it doesn’t seem to help reduce the damp smell. Would putting the 50 pint dehumidifier in the guest bedroom, (where the sump pump is), and then adding a 70 pint dehumidifier to the main area of the finished basement help remove the musty smell?

  63. M. D. says

    This is an excellent review, with clear descriptions, photos and specs I could not find in the manuals, such as the power consumption. Thanks!

  64. Colina says

    Hello you mentioned it is required that we purchase a drainage adapter for this dehumidifier, but do I still need it if I just plan to empty the provided water tank ?
    Also I have a 1750 sq feet house, 2 story plus a basement . my bedroom is 65% humid, where I plan to put the dehumidifier. Is it strong enough to dehumidify my basement if the dehumidifier is in my bedroom upstairs?
    Thank you

    • Admin says

      A drainage adapter is included with your purchase of this dehumidifier. You don’t need to buy one separately. If you run a central AC system on top of running the dehumidifier it should be strong enough to dehumidify your whole house.

  65. george t says

    Excellent review, thanks. What are the reasons for your advise against using an extension cord with these units?

  66. Peter Dimitrov says

    Am inclined towards the newer model, but need a condensate pump, any recommendations of brand, does Frigidaire sell one, or what brand/model do you recommend that will work effectively with this unit. Or where to look for this. Thank you.

  67. Bernard in Ohio says

    The manual says: It is recommended you leave the unit running in the CONTINUOUS setting for the first three or four days until the sweating and dampness odors have stopped. A translation, one hopes. I followed the instructions and humidity plummeted from approx 78% to 45% in 90 minutes. Not good for my brand new grand piano. If I take the machine to another room for a couple of days, humidity will skyrocket. Again, bad for the piano.

    What happens — or doesn’t happen — if I skip the 3- to 4-day break-in period?
    Will the machine be just as reliable and effective?

    When I asked Frigidaire, they told me to run it for 3,4 days. If I don’t, I’m on my own.


    • Admin says

      The recommendation in the manual to run the unit on continuous mode when you first get it is a general recommendation based on the assumption that most users will be placing the dehumidifier in an extremely humid environment with the desire to drastically lower the room humidity in as little time as possible.

      In other words, it’s a recommendation for the environment, not to improve the life of the dehumidifier or anything like that. You should be perfectly fine setting it to a higher desired humidity level when you first get it.

  68. JZ says

    Thank you for the review and this is very helpful.

    I notice you have confirmed many times that this unit will shut off Once the humidity setpoint is reached.
    My question is when the mode is not the Continuous Mode, will it restart when the humidity becomes higher again? At what humidity value will it restart? Thanks!

    • Admin says

      Yes, it will restart automatically once the humidity level in the room goes back up above the set humidity level on the dehumidifier.

  69. Laura says

    I bought the FFAD7033R1 after reading your review and am very happy with it. I recently called the same store for a second unit. My invoice indicated that I was picking up the FFAD7033R1, but apparently the store had substituted FFAP7033T1 because they were out of the one I wanted (I should have checked the box before the salesperson loaded it in the car for me). This model looks similar but has a built in pump. Will it do a similar job or should I insist on what I ordered? Thanks!

    • Admin says

      Unfortunately, we can’t really make a recommendation because we’ve yet to test the FFAP7033T1. We generally do not recommend units with built-in pumps for reasons we talk about in this guide.

  70. Dave Snowdy says

    I’m looking to dehumidify a garage for my antique car because I’m getting white mold spots on the interior. The garage is less than 500sq. ft. with a garage door. The seal is pretty decent. I do have a hotel room type of AC in the garage and I can get the garage pretty cold with it. But I don’t want to run an AC all the time here in Louisiana with months of nearly 100% humidity and 90+ degree temperatures. It doesn’t have a very high SEER rating.
    I do have a drain in the closet that I can pump condensation to.
    I guess I’m asking if a 70 pint is overkill and is it typical to dehumidify a garage that isn’t 100% tight, especially in my climate?

    • Admin says

      A 70 pint unit definitely isn’t overkill. And it’s by no means atypical for you to use a dehumidifier under the conditions you specified.

  71. Christopher Lynn says

    This review is outstanding. I’m not doing any more research. I was becoming nauseous and weary trying to compare the capabilities and tradeoffs of all the different dehumdifiers . The tradeoffs were well-considered and not to be found in any review that I have found. I’m buying the 33R1. Thank you.

  72. Erik says

    Is it safe to put FFAD7033R1 in bedroom (60-75% during summer) overnight while sleeping? The current humidity causes condensation on windows and probably mould issue. Does it have a humistat control which will switch them on and off automatically? Any other less noisy option especially for the bedroom dehumidifier, such as Meaco.. would be appreciated!

    • Admin says

      Yes, this dehumidifier will work quite well in a bedroom at the humidity levels you specified. It will shut off automatically when the room reaches the set humidity. This is one of the most quiet dehumidifiers on the market.

    • Admin says

      Using an extension cord with this particular model or any other compressor based dehumidifier is not recommended by the manufacturer.

  73. Vincent says

    This unit is impressive, but I need one with a built in condensate pump for a crawlspace. What 50 and 70 pint units would you recommend?

  74. Monica says

    The warranty and additional sealed unit warranty on the dehumidifiers need to be mentioned in your results. While Frigidaire gives a one year warranty they have 2-5 years on the compressor. I am now buying my fourth dehumidifier in a little over 6 years as the coils freeze and they stop working. So far they have all been covered by either the manufacturer’s warranty or my credit card warranty that gives an additional warranty over the original manufacturer’s warranty. My latest Frigidaire unit is being replaced under the sealed unit 2-5 yr warranty. I will only consider dehumidifiers with the sealed unit warranty that is critically important and should be referenced in any dehumidifier reviews.

  75. Carl says

    I see they also make this newer unit in 30 and 50 pints models. I have a very small crawlspace, but it is very wet. Things I have read seem to say the space size is the main driver of pint removal need. My space is about 15′ x 20′ and only 4′ high. Would like your thoughts and advice. Thanks.

  76. Michael says

    It was mentioned that a hose adapter is needed for using a standard US garden hose for gravity drain. Is that adapter included? If not, exactly what adapter do I need?
    Also, how far from the bottom of the unit (floor level) is the discharge port?

    Many thanks for this and for the extensive information you’ve provided.

    • Admin says

      A gravity drainage adapter is included with the dehumidifier which allows you to use a standard US garden hose to drain the unit.

  77. Jim Bernard says

    Our basement is 2200 sq.ft. unfinished. Is the big enough to handle that? We’re in coastal Maine. Thanks

  78. Aaron says

    I have a largish one-bedroom apartment (I don’t know the exact square footage — maybe 850 sq. ft.?) that’s quite cluttered with boxes and bookshelves, limiting the options for placing a dehumidifier. The bedroom is where the humidity buildup is creating the most problems, although the bathroom — which has no exhaust fan — is the principal source of moisture. There is also a short hallway between the bedroom, bathroom, and living room where I might place the unit if the cord were long enough. Which position would be best to reduce overall humidity?

    • Aaron says

      Also, how long is the cord? (My apartment was built in the ’50s and has a troublesome shortage of power outlets, with NONE in the hall area that might be the most logical place to put a dehumidifier.)

    • Admin says

      We would recommend placing the dehumidifier in a central location if you can (the way you described your apartment this would be your hallway).

  79. Sharon says

    The block in my basement has become porous and wet with all the northeast rain, so much so I had a severe mold issue and had to have remediation. The contracts has recommended sealing the block and using 2 commercial EnviroBoss dehumidifiers (80 pints water removal AHAM (80°F/60% Rh) to the tune of $2,400. How does this unit compare to a commercial unit like EnviroBoss?

    Thank you in advance for your reply.

  80. Dale says

    I have been using a Frigidaire FAD504DWD for 4 years with good results . I decided to upgrade to the 70pt. FFAD7033R1.
    It is being used in a very well encapsulated crawl space. In general , what speed is most cost effective to run the unit to maintain a 55% humidity level? — high speed to decrease run time , or a lower speed to lower the electrical draw, but with more run time?

    Thank you very much for your great / informative website !!


  81. Sam says

    I would like to reiterate: Thank you for your research and excellent analysis/commentary!

    I have a Hisense 70 pint runs all the time and never reaches the goal. The mfg. says it’s only for 500 sq, ft. So even thought it’s 8 months old I am looking at replacing it.

    My question is:
    My home has 900 sq feet in the basement and 1900 on the first floor. Am I expecting too much from a 70 pint dehumidifier?

    • Admin says

      Setting up a dehumidifier for use over two floors is tricky. If there’s sufficient air flow in the home (provided by a central AC unit or the like) one dehumidifier should still be effective under the conditions you specified. If not, you will need to purchase one dehumidifier for the first floor and an additional unit for the basement.

  82. brad says

    We have had bad luck with a pair of Frederich D70 humidifiers, one of which died after 6 months in our 2300 sq ft. apt. One in MBR and one in LR. Very, very noisy. Results were good (but noisy) for maybe 6 months, and again the one has died. Thought they were the “best” and now not surprised in reading your excellent reviews. Will purchase one (or likely two) of the Frigidaire FFAD7033R1, no. 1 for humidity removal and 2. lower-ish noise.

    Question for you is this; for a 2100 sq ft. 3 level townhome, should we expect the one unit (placed in the utility area with alot of air intake in the basement before going through the smallish Carrier Air Handler unit – and do well with the whole TH? Should we plan on a 2nd unit on 3rd floor somewhere to help? Waterfront TH, windows are not high end, and summer is already humid even with AC. Mid Atlantic area with humidity rates at 80% with temps anywhere from 80 – 99 degrees. (This is a rental TH for us for two years only.) I’m OK to spend the money on a pair, but probably not 3 (one per floor). What would your thoughts be? We are ok with very low humidity levels!

    Finally, I’m so pleased to have come across your site with such fantastic testing, reviews and results. Really impressive – and again grateful; because we all really depend on folks like you. thanks again.

    • Admin says

      I would start with one dehumidifier, placed in the location you specified (by the air handler). If you don’t find that it sufficiently dehumidifies, then purchase an additional unit. Unfortunately, there’s no way to know for sure what will or will not work without testing it in the actual space you need to dehumidify first. That’s why I recommend that you start with as little investment as possible and only purchase additional units if necessary.

  83. David says

    I’ve got a basement with about 1200 square feet of finished space and roughly another 800 square feet of non-finished space that I want to dehumidify. Never really had a moisture problem. Didn’t install air/heat in the basement because it’s always pretty comfortable as is. Is the FFAD7033R1 to much for this space or would I be better off with the 50 pint unit?

    • Admin says

      See our general buyer’s guide for our thoughts on purchasing a 70 pint vs. a 50 pint dehumidifier. The short answer to your question is that this FFAD7033R1 is far from being too large for an 800 square ft. space and would be the better buy compared to its 50 pint equivalent.

  84. Nick says

    What do you know about the hOme 50 dehumidifier? I don’t know who manufactures it but reviews on amazon were very positive.

    • Admin says

      We have yet to test the Home 50 pint dehumidifier and therefore cannot really comment on how it compares to the units we have tested for review.

  85. JEB says

    Concerning the model FFAD7033R1 using Gravity Drainage feature (continuious drainage) , please advise the miniumum size ID and length of hose I am allowed to use. Thank you

    • Admin says

      You can use as short and thin of a hose as you’d like as long as it has standard garden hose connectors. For example, you could use a 1/2″, 5/8″, or 3/4″ hose provided it has a standard connector (which most hoses do).

  86. Brian says

    This is a very nice de-humidifier. Looks great – runs very QUIET. Very impressed with the FFAD7033R1. 30 minutes and all humidity was removed in a connected kitchen and living room. Only issue is the humidity reading is off comparing the to the digital gage I have. Easy to work around. Definitely would recommend this product. Very glad I bought it after reading this article.

  87. Sara says

    Is it worth buying the Asurion extended warranty plan offered for this dehumidifier? Has anyone had experience with this? If something goes wrong, do they cover the cost of shipping the unit back for repair?

    • Anonymous says

      yes, it worth buying. my fad704dwd13 stopped working 14 months after i bought it. had bought the warranty from Asurion. no problem. they gave me full purchase price refund through Amazon to purchase a new one. told me to discard the old one. no hassle. will buy again for my next one.

  88. Jeff says

    You say that it lacks an “auto” mode. Does this mean it keeps running even after it has reached the set humidity level?

    • Admin says

      No, it does not. Auto mode varies from model to model but normally, all it does is automatically set a desired humidity level (without requiring you to manually input a desired humidity level). It’s really more of a gimmick than it is a helpful feature which is why we don’t detract much from this unit’s score in the adjustability category for not having it.

      Read more about “auto mode” here.

  89. John says

    The OLD unit I am replacing draws air from the back and discharges out the front. It is used in the basement that is divided by a wall. I place it to draw air from the side that has the washer/dryer and sump pump and push the ‘dried’ air into the other side. SO, would I be off to buy the FAD704DWD to try and accomplish the same thing? Does the top air discharge come out at an angle to the front of the machine?

    • Admin says

      The FAD704DWD unfortunately doesn’t discharge air at an angle. It discharges it straight up and out of the dehumidifier.

      I don’t believe we’ve tested a unit that processes air the way you describe your old unit doing so. The closest would be the FFAD7033R1 that discharges out of its side.

  90. Joan fry says

    Is the FFAD7033R1 included among the many Frigidaire dehumidifier models that were recalled due to fires. 2.5 million dehumidifier were recalled starting in 2013 and expanded in 2014. The recall included thirteen models of Frigidaire brand.

  91. Jana says

    We purchased this dehumidifier and need to buy a hose for it to drain to a floor drain in our basement. 1- Any suggestions on a reliable hose will work best with this unit? and 2- Do we need to get a pump if the hose is draining downward into a drain that is approximately 5 feet away?

    • Admin says

      Any standard garden hose can be used to drain this unit although shorter hoses will work best (a 5 ft. or 15 ft. hose, for example). If you’re draining downward a pump won’t be required even if the drain is 5 ft. away from the dehumidifier.

  92. Ben says

    If I want to automatically drain with a 3/8″ tube to a drain about 5 feet away, will I need a condensate pump (beside the hose to 3/8″ tube adapter)?

  93. VAB says

    Do you know if the Frigidaire FFADO33R1 will be able to automatically pump and then stop pumping when necessary? I was originally looking for a unit that had built in pump because of need? It will be pumping into a non-floor drain.

  94. Cameron Harris says

    When looking for a dehumidifier to place in one of our offices, I apparently made the mistake of getting an LG, it lasted about 1 week.

    THEN I found the FAD704DWD from Amazon and picked one up right away hoping for a better experience. I was impressed to say the least. We’ve had the FAD704DWD running 24/7 non-stop for over 18 month on full power! Never had a single issue with this dehumidifier. Its fairly quiet just working away doing its job in the back corner, almost forget its even there. We may have cleaned the filter twice at most in the span of 18 months and its no doubt overworked dehumidifying a 1,500sf building with 30ft ceilings! Despite all this it keeps the entire building at 40% humidity (according to the nest thermostat, which btw is installed a great distance away) and it just keeps going!

    We buy all sorts of office equipment, almost on a daily basis and this is the only review in three years ive honestly felt compelled to write simply because Im just that impressed with this dehumidifier and I want to tell anyone looking, THESE ARE THE BEST!

    Im hesitant to buy the new model FFAD7033R1 because the FAD704DWD just works so good and I cant imagine how it could be any better but after reading this buyers guide im going to give it a try get the new model for dehumidifying my house.

    Once the humidity setpoint is reached do both the compressor and fan stop or does the fan run continuously as some other brands do?

    • Nate says

      The fan will keep running for a couple of minutes after the compressor shuts off. The coils are still very cold and are able to remove an extra bit of moisture as the fan forces air over them. After a couple minutes, the fan will also shut off.

      In newer versions of this exact model (manufactured November 2016 and later?), the fan will cycle on a for a couple of minutes, without the compressor, only to allow the hygrometer a more accurate reading. The fan will cycle routinely throughout the day just to measure the humidity. Otherwise, the hygrometer will continuously display very high (false) humidity levels. Listen carefully, and you might notice only the fan is running once in a while for a couple of minutes *without* the compressor. This is a smart feature to routinely sample the air.

        Nate –

        Thanks very much for making your comment. This was my concern precisely: the machine seems to turn on even when the hygrometer reads a little lower that the RH I specified. Frigidaire could not give me this explanation. Did you determine this just by listening closely?

    I use my unit in an encapsulated crawl space and turn the unit off in cold winter months by pressing power off button. Will setting be saved when I turn unit back on using power button. I don’t unplug unit. Thanks.

    My house is approx 980 sq feet.

    It has two bedrooms adjacent to each other, each approximately 120 sq feet.

    The bedrooms are at the end of a hall that is 4 feet wide and 10 feet long.

    The rest of the house (living room, kitchen, dining room and Florida room) is a common area, with no separating walls, that measures approx 675 sq feet.

    My question is this … If buy a 70-pint dehumidifier and put it in the middle of the above-described “common area” (675 sq. ft.) will it be able to dehumidify the two bedrooms that are down the aforementioned hall 4 feet wide by 10 feet long?

    • Admin says

      Yes, it should. But it will take much longer than if you were to put the dehumidifier within the actual rooms that you want to dehumidify. If you’re set on keeping the dehumidifier in the common area you could put some fans in the bedrooms to help circulate air throughout the house. This would greatly improve the efficiency of the dehumidifier in dehumidifying the whole house.

    Which dehumidifiers work best at higher ambient temperatures? I expect to go above the 97 degrees F that the Frigidaire is rated for. My size would be in the 30 to 50 pint per day capacity range. The unit also has to restart automatically after a power outage.

    • Admin says

      Your options are unfortunately very limited if you want to consistently operate a dehumidifier in temperatures above 97 degrees.

      Both the EcoSeb DD122EA-Classic and DD322EA-Classic can be operated in temperatures up to 104° F. These units are really your only consumer-grade options.

      Otherwise, both the Dri-Eaz LGR 2800i and LGR 3500i can be operated in temperatures up to 125° F. However, they are both very expensive commercial grade dehumidifiers. You can read more about them in our commercial dehumidifier buyer’s guide.

      In all honesty, for an especially warm space such as the one you described, you would probably be much better off using a regular consumer-grade compressor based dehumidifier (such as the FFAD5033R1 if you’re looking for a 30 or 50 pint unit) in conjunction with a portable AC unit instead of using any of the dehumidifiers we mentioned above above.

    I want to get a dehumidifier for my RV, it is only 24′ long and about 8′ wide (~ 1500 cu ft). I live in the Pacific Northwest, it rains a lot starting in October and ends sometime in May/June. I know you say larger is better, but is the 70 pint unit too big for this size of space? Does the Frigidaire unit shutdown at a set temperature? I have a heater in the RV that is connected to a Thermocube so when the temperature gets down to 35 then the heater will run until it gets up to 45.

    • Admin says

      If you’re looking for something smaller in size that’s going to work great at lower temperatures our recommendation would be either one of these two desiccant units:

      More expensive with more features:

      Less expensive with less features but with the same capacity as the unit above:

      Both units are much smaller in size than the FFAD7033R1 and either will work much better at temperatures below 40 degrees.

      At temperatures above 40 degrees the Frigidaire is going to give you much better dehumidification but it is much larger in size. The FFAD7033R1 measures about 15 inches wide, 12 inches deep, and 25 inches high. The Ecoseb units are about 11 inches wide, 7 inches deep, and 19 inches high. It doesn’t sound like much of a difference but they are actually quite a bit smaller (not to mention lighter) than the Frigidaire.

      To summarize:

      If you want maximum dehumidification and superior reliability, don’t need the unit to work at temperatures below 40 degrees, and can deal with an appliance as big as the Frigidaire in your RV, it would be our recommendation.

      If you want something that’s going to give you dehumidification below 40 degrees and is going to be quite a bit more manageable (smaller and lighter) in a space such as an RV then our recommendation would be either one of the Ecoseb desiccant units.

      A compromise between these two options would be the 30 pint FFAD3033R1 (see our review for it here). It’s still not going to work very well below 40 degrees but, assuming your heater keeps the space above 40 degrees, will offer better dehumidification than the Ecoseb units (30 pints instead of 15 pints of dehumidification per day) and is still smaller (it’s roughly 11x14x21 inches) than the FFAD7033R1. Note that the 50 pint FFAD5033R1 is just as big as the 70 pint unit.

    I own the FAD704DWD model for last two years, this unit is amazing. Only issue so far is clean air filter light comes on way to soon after cleaning. And the handle design on bucket isn’t strongest, ended up breaking after a few months. Bucket still easy to lift without handle though.

    • Admin says

      No, the unit doesn’t need to be raised. The condensate pump will work just fine if it’s placed at the same level as the dehumidifier.

  101. Doug Kelsey says

    What about a power loss? Does this unit come back on when power is restored or must it be manually restarted?
