Quick Review Summary
The EcoSeb DD122EA-Classic is a full size feature rich desiccant dehumidifier. In the review that follows we jump right into discussing the DD122EA-Classic’s features and functionality and how they compare to those found on compressor based units. We then transition into a discussion of how these same features and this same functionality affect this unit’s energy efficiency, noise output, and moisture removal rate. At the end of this review you’ll find a detailed comparison of this unit to other three desiccant dehumidifiers from EcoSeb and which of the four we recommend over the others.
The DD122EA-Classic does come equipped with a built-in humidistat but the dehumidifier’s control panel does not display the humidistat’s reading. Most compressor based dehumidifiers show the ambient air’s humidity level on their control panels. For example, if the humidity in the room you need to dehumidify is 70% the dehumidifier will show that the room humidity is 70%. This EcoSeb unit will not show you what the room humidity is.
The DD122EA-Classic does come equipped with a timer but the timer will only allow for a delayed stop, not a delayed start (as is standard on many compressor based units). The EcoSeb also doesn’t allow for much flexibility in terms of how the timer is set. Most compressor based units can be set to a delayed start or stop in half hour increments up to 10 hours and then 1 hour increments from 10 hours up to 24 hours. This EcoSeb unit can only be set to a delayed stop in 2, 4, or 8 hours.
Number of Fan Speeds
This unit doesn’t come equipped with the standard two or three fan speeds (high, medium, and low) that you’ll find on most compressor based dehumidifiers. Instead, it has multiple automatic modes that dictate fan speed. We discuss those modes in detail below.
The DD122EA-Classic is a feature rich dehumidifier that trades in the flexibility that you’ll find in most manually programmable compressor based dehumidifiers for the comfort of being able to automatically set and forget the dehumidifier depending on the setting/application that you need the dehumidifier to operate in.
Most compressor based dehumidifiers allow you to manually set the desired humidity in the room you need to dehumidify. For example, if you want the room to have a humidity level of 40% relative humidity, you manually input 40% on the dehumidifier’s control panel. The dehumidifier will then dehumidify until its built-in humidistat senses that this desired humidity level has been achieved. When this occurs the dehumidifier automatically shuts off its compressor and fan (it stops dehumidifying) for as long as it senses that the room humidity is at or below the desired humidity level of 40%. As long as the dehumidifier is on it will continually monitor room humidity and turn on/off repeatedly depending on whether the room humidity is above (compressor/fans on) or at or below (compressor/fans off) the set humidity level of 40%.
The DD122EA-Classic doesn’t allow you to set the humidity level to any specific percentage. Instead, it features several automatic modes that will automatically set room humidity to a predetermined range. These modes will also dictate how much power the dehumidifier uses. More demanding modes (those modes in which the dehumidifier will need to “work harder”) will require the dehumidifier to draw close to the maximum specified wattage for this unit – 615 watts. Those modes in which the dehumidifier isn’t “working” quite as hard will require the dehumidifier to draw less power – closer to the minimum specified required wattage for this unit – 330 watts.
The first unique mode featured on this dehumidifier that we’ll discuss is laundry mode. Laundry mode is the equivalent of a “continuous mode” on a compressor based dehumidifier. The dehumidifier won’t shut on or off, adjust fan speed, etc. when set to this mode. It will run continuously for as long as this mode is active. The DD122EA-Classic features two different laundry modes – normal laundry mode and turbo laundry mode. Normal laundry mode will set the dehumidifier to run continuously but not at maximum power. Turbo laundry mode will set the dehumidifier to run continuously and at maximum power.
This mode is called “laundry mode” due to the fact that this type of dehumidifier is much more prevalent in parts of the world where an electric dryer isn’t used to dry clothes. Instead, people dry their clothes on a drying rack. This type of dehumidifier can be used to dry clothes hanging on a drying rack more quickly. For it to dry clothes most efficiently you want the dehumidifier to run continuously and potentially on its highest setting (turbo mode). Hence why this mode is called laundry mode.
For those of us who live in the United States, laundry mode can be used exactly the same way continuous mode is used on a compressor based dehumidifier. Simply set the EcoSeb to turbo laundry mode so that it can run continuously on its highest setting. This will allow the dehumidifier to dehumidify a very large and/or very humid room as quickly as possible. In many of our reviews for compressor based units we suggest that when first starting to dehumidify a very humid room you first run your dehumidifier on continuous mode for a few days until room humidity reaches a point where it’s no longer perpetually severely humid. At this point you’re no longer trying to lower room humidity. Instead, you’re simply trying to maintain room humidity. When room humidity reaches the point at which you’re simply trying to maintain a comfortable humidity level you can turn off laundry mode (continuous mode) and use different settings which we discuss next.
Dry mode on this dehumidifier is the mode you’re probably going to be using most of the time. EcoSeb makes the claim (a claim that we wholeheartedly agree with) that comfortable room humidity is somewhere between 40% and 60% relative humidity. At humidity levels below 40% the air starts to become excessively and uncomfortably dry. At humidity levels above 60% the air feels uncomfortably damp. So, all three dry mode settings for the DD122EA-Classic will automatically set the dehumidifier to a desired humidity level somewhere between 40 and 60%.
The first selectable dry mode is auto. On auto mode the dehumidifier is set to run so that a room humidity level between 50% and 60% is achieved. On this mode the dehumidifier is limited to setting room humidity no lower than 50% humidity. This achieves two things. First, it allows the dehumidifier to set room humidity to a humidity level that’s relatively comfortable. Second, it allows the dehumidifier to save power as it doesn’t need to work as hard as it would need to work to achieve a lower humidity level such as 40% relative humidity.
The second selectable dry mode is economy. For this mode EcoSeb doesn’t specify the exact humidity range that the dehumidifier is set to. We feel it’s safe to presume that this is because no exact humidity range is set when this mode is selected. The dehumidifier most likely runs on a low power setting that still allows it to dehumidify but not “aggressively” and not for the sake of reaching a set humidity range. It just dehumidifies, slowly. EcoSeb does specify that the dehumidifier will run on its most quiet setting on economy mode and that this mode is “highly recommended for night use”.
The third selectable dry mode is hi. On hi mode the dehumidifier will run until a room humidity level of 40% to 45% is achieved. This mode uses more power and will increase fan speed (and the noise output that goes with it) for the sake of dehumidifying more “aggressively” and reaching lower more difficult to reach humidity levels.
Our recommendation is that you use auto mode unless you find 50% relative humidity uncomfortable. If this is the case, use hi mode. Only use economy mode if the room you need to dehumidify is either very small and/or is only mildly humid. You can also use economy during night time as the manufacturer suggests if you need to dehumidify the same room that you’re sleeping in and you find the dehumidifier running on higher settings to be bothersome.
The two modes we’ve discussed thus far act autonomously. In other words, dry mode and laundry mode cannot be selected at the same time. Any of the sub modes that fall under these modes also cannot be selected at the same time. For example, you can only set the dehumidifier to auto mode or economy mode or hi mode. You can’t set it to auto mode and economy mode at the same time.
The two modes we’ll discuss next do not act autonomously. You can select a particular swing mode and turn the unit’s ionizer on/off while setting it to any of its dry modes or any of its laundry modes at the same time. Thus, you’ll have to set both of these modes at least one time when first setting up the dehumidifier. That being said, let’s start our discussion of this unit’s swing modes.
Air that’s exhausted out of a compressor based dehumidifier moves in one direction. Air that’s exhausted out of the DD122EA-Classic behaves quite differently. This is because the mechanisms by which air exhausts out of the EcoSeb are much different than the mechanisms by which air exhausts out of a compressor based dehumidifier. On a compressor based unit a single large fan exhausts air out of either the top, back, or side of the dehumidifier through a plain grille. Air moves in a straight path out of this type of dehumidifier. On this EcoSeb unit a blower (similar to a fan) exhausts dehumidifier air through the top of the dehumidifier, but on its way out the air goes through two different additional mechanisms that alter its path.
The first mechanism it goes through is what EcoSeb calls a 3D louvre. This louvre consists of a cylinder that holds a number of small discs. Imagine the cylinder being an axle and the discs being wheels on the axle. As air exhausts out of the dehumidifier it passes through the 3D louvre which alters the path of the air depending on the orientation of discs. Their orientation can be adjusted by hand by rotating a wheel on the end of the cylinder to which they’re attached. The discs can be rotated so that they spread the air moving through them for “wide airflow” or push the air exhausting together for “spot airflow”. Wide airflow allows for a more even distribution of dehumidified air which improves the dehumidifier’s overall efficiency (how quickly it takes to dehumidify all of air in the room) while spot airflow allows you to send the air in a particular direction if there’s a particular area in a room that you want dehumidified more quickly. As we mentioned in our discussion of this unit’s laundry mode above, in some parts of the world this type of dehumidifier is used to dry laundry. You would definitely want to adjust the dehumidifier’s louvre for spot airflow if you’re using it for this purpose.
As air exhausts out of the DD122EA-Classic it first goes through the unit’s 3D louvre and then gets its path altered once again by an additional blue transparent louvre that acts to dictate the direction in which the exhausted air is “pushed” as it leaves the dehumidifier. This additional louvre is more of a shield than a grille. It doesn’t allow air to pass through it but instead directs air around it. Recall that air is either moving spread out or in one direction as dictated by the dehumidifier’s 3D louvre. This air would simply exhaust straight up out of the dehumidifier without this additional transparent but solid blue louvre. This additional louvre can “swing” in different directions and thereby dictate the direction of airflow.
There are four selectable swing modes that alter the swing of this additional blue louvre. On the first mode, up, the louvre will swing upward in a range of approximately 100°. In this mode the air will exhaust in a cone shape out of the top of the dehumidifier. The cone shape measures 100° across.
On the second mode, front, the automatic transparent louvre will swing so that air exhausts out of the front of the dehumidifier in a cone shape that measures only 50° across.
On the third mode, wide, the louvre will swing in a wider range of approximately 150°. In this mode the air will exhaust in a cone shape measuring 150° across out of the front and top of the dehumidifier.
Finally, you can hold the swing mode button for several seconds to hold the swing of the louvre in a particular direction.
The DD122EA-Classic also comes equipped with an air ionizer that “effectively purifies the air (exhausting out of the dehumidifier) with negative ions and silver ion filtration”. Thus, this dehumidifier not only dehumidifies, but also purifies the air that it processes. As this is a dehumidifier review and not an air purifier review website, we didn’t take the time to research how effective this type of air purification might be. Regardless, we find it impressive that such a feature is included with this dehumidifier.
The DD122EA-Classic draws between 330 and 615 watts of power depending on mode and setting. Modes that involve the dehumidifier running at maximum capacity (for maximum moisture removal) will require for it to draw close to or exactly 615 watts of power. Economy power saving modes (which don’t allow for nearly as much moisture removal) will require that the dehumidifier draw closer to or as little as 330 watts of power. If you want this unit to remove as much as the advertised maximum amount of 15 pints of moisture per day it will draw closer to or exactly 615 watts of power. At lower power levels it will remove much less moisture per day.
How does this dehumidifier’s energy efficiency compare to that of compressor based units? The answer to this question largely depends on the size and capacity of the compressor based dehumidifier we’re comparing it to. Small capacity 30 pint/day compressor based units draw on average 300 to 400 watts of power. Large capacity 70 pint/day units draw on average 700 to 800 watts of power. Note that these are maximum power draw averages and so we need to compare them to the DD122EA-Classic’s maximum power draw of 615 watts. Clearly, the EcoSeb is less energy efficient than both small capacity 30 pint and large capacity 70 pint compressor based dehumidifiers. It removes half as much moisture per day (15 pints vs 30 pints) as small capacity compressor dehumidifiers but uses about twice as much energy to do so (615 watts vs 300 to 400 watts). It removes more than 4 times less moisture than large capacity compressor dehumidifiers and uses only slightly less energy to do so (615 watts vs 700 to 800 watts).
A major factor here is the time it takes for a dehumidifier to dehumidify a particular room. A 70 pint unit may draw more power than a 30 pint unit, but, it also dehumidifies at a much higher rate of speed. Thus, it needs to draw its maximum amount of power (700 to 800 watts) for a much lesser period of time to dehumidify the same quantity of air. A 70 pint unit may need to run for only 2 hours to dehumidify the same space that would take a 30 pint unit 6 hours to dehumidify. If this is the case the 70 pint unit is more cost effective as energy is billed per kilowatt hour, not per kilowatt. 700 watts times 2 hours is less expensive than 300 watts times 6 hours.
These same principles apply when assessing the cost of running the DD122EA-Classic on different settings. It may only require 330 watts of power to run on economy settings, but on these same settings it will take a much longer period of time to dehumidify the same space than if you were to run it at maximum power for maximum moisture removal. The bottom line is that despite the fact that it’s capable of running at very low power levels, the DD122EA-Classic is not necessarily a more energy efficient dehumidifier on these settings (as compared to maximum power draw settings) and as we clearly demonstrated above is also not more energy efficient than a compressor based dehumidifier.
The DD122EA-Classic according to its manufacturer specifications produces 33 dB of noise on its quietest setting. Noise output readings are largely dependent on how far away the measuring device is from the source of the noise. Thus, it’s difficult to compare this given noise output of 33 dB to that of the measured noise output of the compressor based dehumidifiers that we tested, as we don’t know how far away from the dehumidifier the manufacturer’s reading was taken.
Even though we were unable to test the DD122EA-Classic for noise output, we were able to test a very similar desiccant dehumidifier, the SPT SD-014V. The SPT was measured at 61.1 dB of noise output at close range (sound meter placed right about the dehumidifier’s control panel) on high fan speed and 45.5 dB at the same range but on low fan speed. The SPT had a measured noise output of 47.3 Db at long range (sound meter placed 10 ft away from the dehumidifier) and a level below 40 dB (the sound meter we used could only measure levels above 40 dB and at this range and on this setting it could not show a registered value) at the same range but on low fan speed.
For comparison, the 70 pint compressor based dehumidifiers we tested had a measured average of 67.2 dB of noise output at close range on high fan speed and 63.4 dB at close range on low fan speed. They were measured at an average of 53.5 dB at long range on high fan speed and 50.3 dB at the same range but on low fan speed.
The take away here is that, presuming that the SPT SD-014V and DD122EA-Classic are similar in terms of their noise output, the DD122EA-Classic is much quieter than even the quietest compressor based dehumidifier. Outside of the data we’ve gone over above, consider the method by which desiccant dehumidifiers and compressor based dehumidifiers dehumidify. Desiccant units have a fan but no other moving parts. Compressor based units have a compressor on top of multiple fans that all produce noise. Any desiccant dehumidifier, including the DD122EA-Classic, is recommended over a comparable compressor based dehumidifier should you value noise output over moisture removal rate.
The DD122EA-Classic removes up to 15 pints of moisture per day. Note that this manufacturer specified moisture removal rate is taken at 68° F and 60% relative humidity. Most compressor based dehumidifiers have their manufacturer specified moisture removal rate measured at temperatures and humidity levels that are conducive to maximum moisture removal for a compressor based system – 80° F and 60% relative humidity. At any conditions outside of these ideal conditions a compressor based dehumidifier will operate with reduced efficiency and remove less than the manufacturer specified amount of moisture per day.
The important take away here is that the DD122EA-Classic’s moisture removal rate does not fluctuate with temperature and relative humidity levels which is definitely the case for the moisture removal rate of any compressor based dehumidifier. A 70 pint compressor based unit removes 70 pints of moisture per day, but only if the temperature and humidity level is close to ideal conditions – 80° F and 60% relative humidity. If the temperature drops down to 50° F and/or the humidity drops down to 50% RH, the same dehumidifier won’t remove nearly as much as 70 pints of moisture per day. The same isn’t true for any desiccant dehumidifier including the DD122EA-Classic. Regardless of temperature and humidity (as long as the temperature falls within the manufacturer specified operating ranges) the dehumidifier will always be able to remove 15 pints of moisture per day. At 40° F and 60% RH it will remove just as much humidity as it removes at 95° F and 90% RH.
Operating Temperature Range
The DD122EA-Classic can be operated in temperatures ranging from 34° to 104° F. This is a much larger operating temperature range than what you’ll find on the average compressor based dehumidifier, not only in terms of what is specified by the manufacturer but more importantly, in terms of what the dehumidifier is actually capable of. Most manufacturers of compressor based dehumidifiers specify a recommended operating temperature range of about 41° F up to about 90° F. However, specifying such a range doesn’t tell the whole story.
The process by which compressor based dehumidifiers dehumidify requires that they cool the air they’re processing to dehumidify it. It also requires that the moisture that is removed from the air change state from a vapor to a liquid. Moisture can only be removed from the air in its liquid form.
Desiccant dehumidifiers such as this EcoSeb unit do not require that air be cooled or that the moisture they remove from the air change state. For both reasons they’re able to remove moisture from the air at a much wider range of temperatures.
Compressor based units drop in efficiency as soon as temperatures fall below around 80° F. Desiccant units have similar efficiency no matter if the temperature is 34° F or if its 104° F. Due to the fact that they require moisture to change into liquid state to remove it from the air, compressor based units also build up frost on their evaporator coils at lower temperatures (around 60° F), further reducing their efficiency. Desiccant units such as this EcoSeb unit do not create any frost during the dehumidification process. The bottom line – any desiccant dehumidifier (including this one) is a better option than a compressor based dehumidifier at extreme temperatures.
Most compressor based dehumidifiers have a threaded outlet to which you can attach a standard garden hose to drain them using gravity (and thereby avoid having to continuously empty their water tanks). This EcoSeb unit requires that you permanently knock out a piece of plastic (that’s already been weakened for this purpose) on the outside of the dehumidifier to insert an included drainage hose in order to employ gravity drainage. The included drain hose is short (3.3 ft) and not very wide in diameter (about 7/16 inches in diameter).
Ease of Use
The DD122EA-Classic has a raft of settings that the average consumer isn’t going to be able to use without first perusing its manual. To first start using the average compressor based dehumidifier you simply take it out of the box, plug it in, set a desired humidity level and fan speed and you’re done. On this EcoSeb unit you’ll definitely need to read the manual first to figure out what all its buttons do and how to setup the dehumidifier for your particular application.
Filter Removal Difficulty
The filter on this unit is very easy to remove and replace. The average compressor based dehumidifier requires that you remove its water collection bucket before gaining access to its filter. The same isn’t required on the DD122EA-Classic. The filter is very easily accessed on the side of the dehumidifier.
Due to the fact that it’s required reading, the manual for this unit needed to be lucid for us to understand how to use it. Thankfully, this dehumidifier’s manual is very well and clearly written with as many high quality diagrams/illustrations as are needed to understand how to use it correctly. The DD122EA-Classic’s manual is far more detailed and complete than any manual for any compressor based dehumidifier we’ve reviewed, but, like we’ve alluded to previously, this is also much more necessary for this type of dehumidifier than it was for any compressor based unit we’ve reviewed.
Water Tank Size
The DD122EA-Classic has a 4.2 pint water tank. Compared to those water tanks found on similarly priced compressor based units it’s extremely small. The top rated Frigidaire FFAD7033R1, for example, a 70 pint compressor based dehumidifier, has a 13.1 pint tank. Not nearly as well rated but another example of a 70 pint compressor based dehumidifier is the Kenmore KM70. It comes equipped with a gargantuan 19.2 pint water tank.
The difference in size between the DD122EA-Classic’s water tank and other desiccant dehumidifiers’ water tanks isn’t nearly as large. The DD322EA-Classic and Simple both come equipped with 7.4 pint water tanks.
Durability (Build Quality)
See our DD122EA-Simple review for more information on the durability of this type of dehumidifier.
Portability is definitely one of this dehumidifier’s (and really any other desiccant dehumidifier’s) strong suits. Large capacity compressor based units weigh a minimum of about 40 pounds with many weighing close to 50 pounds. The DD122EA-Classic weighs a mere 13.2 pounds. It’s also lighter than both the DD322EA-Classic and Simple which both weigh 18.7 pounds. The DD122EA-Classic is a very light highly portable dehumidifier. If you need to dehumidify more than one room or space and will need to constantly move the dehumidifier you end up buying from one location to the next then definitely take this unit’s light weight into consideration.
All EcoSeb dehumidifiers come equipped with an impressive 2 year warranty. Compare this warranty duration to the 1 year limited warranty that comes with most large capacity compressor based dehumidifiers. Those units also come with a 2 to 5 year additional warranty on their sealed systems (which includes the dehumidifier’s compressor, sealed tubing, etc.) but the limited 1 year warranty is obviously much more comprehensive and the warranty you’re much more likely to need honored should something go wrong with the dehumidifier during your first few years of ownership.
The additional 1 year warranty you get with these EcoSeb units is a big deal. Dehumidifiers are unfortunately less durable appliances than they should be and thus having protection against something breaking on them is important. Having an additional 1 year of protection on the DD122EA-Classic is definitely yet another variable you should give strong consideration to if you’re debating between purchasing it or a similarly priced compressor based dehumidifier.
The DD122EA-Classic retails for around $250. The DD122EA-Simple, priced at approximately $190, removes just as much moisture per day (15 pints) but doesn’t come with nearly as much features as the DD122EA-Classic. More expensive EcoSeb units remove more humidity per day. The DD322EA-Classic comes with almost the exact same features and functionality as the DD122EA-Classic but retails for a whopping $340 (approx.) due to its greater moisture removal capacity of 21 pints per day. The DD322EA-Simple has the same features and functionality as the DD122EA-Simple and retails for around $280 with its same greater capacity of 21 pints per day.
The DD122EA-Classic is very similarly priced to the top rated Frigidaire FFAD7033R1 and many other 70 pint compressor based dehumidifiers we’ve reviewed. The Frigidaire also retails for about $250. As such, in wrapping up this review, we will not only compare the DD122EA-Classic to other desiccant dehumidifiers from EcoSeb, but will also be comparing this unit to the best example of a 70 pint compressor based dehumidifier, the aforementioned FFAD7033R1.
As to whether we recommend that you purchase the DD122EA-Classic (or any other EcoSeb desiccant dehumidifier) or a compressor based dehumidifier – first decide what your needs are and which dehumidifier type fits those needs. If the environment you need to dehumidify is very cold (below 50° F) or very hot (above 90° F) a desiccant dehumidifier can be just as heavy duty (remove just as much moisture) as a similarly priced compressor based unit. If the environment you need to dehumidify is close to ideal dehumidifying conditions for a compressor based unit (80° F and 60% RH) you’d be much better served (get a much better bang for your buck among other things) with a compressor based unit. A desiccant dehumidifier runs more quietly than a compressor based unit – if this is important to you definitely take this into consideration. Desiccant dehumidifiers are also much lighter and portable than compressor based units – again, take this into consideration if this is an important factor for you. These EcoSeb units have other advantages over compressor based units also – a good example is their 2 year warranty. In any case, decide whether what a desiccant dehumidifier offers you is necessary and/or preferred over what you get in a similarly priced compressor based unit and go from there.
Desiccant Dehumidifier Recommendations
Let’s assume that you need or prefer a desiccant unit. In this case, options are limited. These EcoSeb dehumidifiers are really the only option out there. The SPT SD-104V is discontinued. Other full size desiccant units either have terrible consumer reviews our have outrageous prices. Among the dehumidifiers that EcoSeb manufacturers you have four choices – the DD122EA-Classic, DD122EA-SIMPLE, DD322EA-Classic, and DD322EA-SIMPLE.
Our recommendation regarding these four units is the following: Decide what about these dehumidifiers is most important to you and go from there. For many consumers the most important factor dictating their purchase decision will be price. In this case, the DD122EA-SIMPLE is an excellent option. It’s affordable (at least compared to compressor based units) at $190 (approx.) and removes just as much moisture per day as the DD122EA-Classic at the cost of having less features.
That being said, should you be able to afford the DD122EA-Classic at $250 (approx.) it gets our highest recommendation among all full size desiccant dehumidifiers on the market. It comes with a myriad of features not found on the DD122EA-SIMPLE, some of which you won’t even find on the much more expensive DD322EA-Classic. The flexibility that its dry modes and laundry modes gives you is invaluable. Most valuable, however, is its swing modes. Being able to direct the air that exhausts out of the dehumidifier in a particular direction or spread it out over a particular area makes for much more efficient dehumidification. The DD122EA-Classic also has an adjustable 3D louvre, something that you won’t find even on the 322EA-Classic version. Being able to adjust the 3D louvre allows for even further flexibility in directing air that exhausts out of the dehumidifier. Finally, the DD122EA-Classic comes equipped with an ionizer (once again you won’t find this even on the most expensive EcoSeb desiccant dehumidifier, the DD322EA-Classic). Being able to not only dehumidify but purify air with the DD122EA-Classic makes it the ultimate in-home air quality appliance.
The next most expensive dehumidifier from EcoSeb is the DD322EA-SIMPLE. Our recommendation is that you only buy this dehumidifier if you absolutely need the extra dehumidification power that it provides (it has a 21 pint per day moisture removal rate vs the 15 pint per day rate of both 122EA units). It’s more noisy than both 122EA units and it’s also slightly heavier. This unit also has the same features and functionality as the approx. $90 less expensive DD122EA-SIMPLE, meaning that it has less features and more limited functionality than the approx. $30 less expensive DD122EA-Classic.
Finally, the approx. $340 DD322EA-Classic is only recommended for those consumers who are looking for the same type of features and functionality present on the DD122EA-Classic but who are also looking for more dehumidification power. Like the DD322EA-SIMPLE, the Classic has a 21 pint per day moisture removal rate. Note that despite the fact that it shares almost an identical control panel (and the features and functionality that go with it) to the DD122EA-Classic, the 322 version does not include an ionizer and also doesn’t come equipped with a 3D louvre.
Have a question or comment? Let us know below.
Can someone tell me how to attach a 7/16″ hose tubing to this unit in order to have continuous drainage?
Hey, is the ionizer safe to use? I don’t see a ppm rating on this.
Very well written, concise article. We have a new house that is so air tight that moisture condenses on the windows when temps drop to 20 or less. Our average rh is 45 to 50. I am purchasing the EcoSeb after reading this. I have tried using exhaust fans more frequently and not leaving standing water in the sink along with getting rid of a few large leaved houseplants and not using a drying rack. I tried our compressor style dehumidifier but it didn’t seem to pull much moisture in a 60 degree bedroom. Hoping for better results with EcoSeb.
Thanks for the great information. Very informative.
I’m looking to buy a new dehumidifier and was interested in the 70 pint Frigidaire. I currently have the Frigidaire . It’s been great. Using it over five years.
One big difference I see – On my older model, FAD704DWD the air intake is on the front of my unit. Whereas on the newer units, the air intake is located on the back.
I’m concerned that I will no longer be able to plug it in (six feet cord)
and simply leave it close to the wall (not up against).
Will the new unit’s air intake be blocked? I’d rather not have to stand the unit backwards. Why did they make this change?
Your thoughts please. Most companies seem to have the air intake on the front, which to me, makes better sense.
You need very little clearance for the dehumidifier to be able to properly intake air from the back. Newer units, with their intake on the back, work very well even if they’re close to the wall.
I have a new home with a 1500 sq ft concrete basement. The temperature is 56 degrees and the humidity is 75. I would like an oversized dehumidifier. I am thinking a desiccant dehumidifier would be best because the temperature is always cool in the basement. Please advise.
Over the past 4 years, I have had 3 Ecoseb 21 pint and 3 Frigidaire 70-pint dehumidifiers. In each case one of the 3 was a replacement for a failed product. One EcoSeb started overheating and had a high whine about 1.5 years in; their service engineer had a few questions, they picked up the failed unit and sent me a new one. Frigidaire replacement was a failed motor; just under the warranty limit. I drove the unit back to the store – had to debate the problem [close to warranty] and then the store replaced it.
In our New England basement, the Ecoseb operates to below freezing [outside] because it’s still 40 degrees inside, then shuts off. The Frigidaires keep operating – even though there’s no moisture being removed – annoying. In both cases, there is not a floor drain – the EcoSeb must be emptied more often [we empty the EcoSeb drawer to a pail, then carry the pail to a sink] but the drawer system works. The Frigidaire holds more water – but its tank is quite heavy when full; also, two plastic handle attachments have broken.
The EcoSeb is relatively quieter, even at higher speed. The longer time to dehumidify a new space doesn’t matter to us because we aren’t moving it from room to room. When first using, it will take a couple of days to dehumidify; then low speed is fine – so, for us, it is more energy efficient than the larger Frigidaire. Since both units go 24/7, I did notice this in the electric bill – before I realized that the Frigidaire wasn’t actually dehumidifying [my bad, but annoying].
I am about to buy another EcoSeb; it works, it’s quiet and efficient. I have a dry storage area in the basement [so dry, no spiders live there!]
I have a finished half-basement master bedroom that is about 200 square feet. There are windows across one side, and then the opposite side is below grade. It is pretty humid down there, but we’re very noise sensitive and this is a bedroom. So I had a Statler Form Albert but it quit on me ($500 down the tubes). We are trying to figure out what to do next. I was away all summer and came back and saw some small mold spots on a few clothing items in the (open) closets. And the floating floor has swelled a bit. Yikes! Based on your info I figure the little Thermo-Electric ones are not big enough to do the job. So then the choice is between the quietest compressor models (Frigidaire) and the most vigorous desiccant models (EcoSeb Classic). I would be aiming to run this in continuous mode just during the humid summer months (June-early September), and I am away much of that time so we need to be able to use the hose (probably will make a small hole thru the wall so the hose can drain into the bathtub). I would be very grateful for any advice you might have – Thank you!
Any of our top picks (compressor based units) will work just fine for your application.
Our unit is releasing a bad odour while in operation. We have cleaned the filter numerous times. Is there another filter on the unit?
You’re smelling the desiccant in action. We have a couple and you typically notice it when it’s running hard for extended periods or when it’s not run for a while. It’s just something you have to get used to. It happens seldom enough that it doesn’t bother us.
