30 Pint Dehumidifier Reviews

Thus far we’ve only tested four different 30 pint dehumidifiers. We’ve limited our testing in this size class for two reasons. The first reason is that there really isn’t a large selection of dehumidifiers to choose from in the 30 pint size class. Manufacturers tend to focus on 50 and 70 pint units and many don’t release smaller capacity dehumidifiers. Keystone, for example, manufacturers both the KSTAD70B, a 70 pint unit, and the KSTAD50B, a 50 pint unit. They simply do not manufacture a 30 pint dehumidifier. The same is true for many other manufacturers.

The second reason why we’ve tested so few 30 pint dehumidifiers is because we really do not recommend that potential dehumidifier buyers purchase a 30 pint dehumidifier to begin with. As we discuss in our general buyer’s guide, many consumers look into buying a smaller capacity dehumidifier for the wrong reasons. Many think that 30 pint dehumidifiers are quieter and more energy efficient than their 50 pint and 70 pint counterparts. This simply isn’t the case. 30 pint dehumidifiers are in fact much less energy efficient (as we discuss here) and just as noisy (see here) as their larger capacity counterparts. The only reason why you should be considering a 30 pint dehumidifier is if one, the space you’re going to be dehumidifying is very small or if two, the environment that you plan on dehumidifying isn’t severely and/or perpetually humid.

As a final blunt warning do not buy a 30 pint dehumidifier if you’re trying to save money. Not only are they less energy efficient (costing you more in energy costs over time), but they also do not cost much less on average than their larger capacity counterparts, 50 pint dehumidifiers especially – the average cost for the 50 pint dehumidifiers we’ve tested is $212 while the average cost for the 30 pint dehumidifiers we’ve tested is $198. 70 pint dehumidifiers are substantially more expensive, on average ($254), although the top rated Keystone KSTAD70B can be bought from reputable merchants online for a mere (approx.) $190. The top rated 30 pint Frigidaire FFAD3033R1 retails for about $180. For a list of our top rated 70 pint dehumidifiers click here and for our list of top rated 50 pint dehumidifiers click here.

Best Rated 30 Pint Dehumidifiers – 2017 Overall Rankings

#1 Frigidaire FFAD3033R1

(click on the model for our review and buying options)

The Frigidaire FFAD3033R1 is by far the best 30 pint dehumidifier currently on the market, if only because it has little to no competition in the size class. The three other 30 pint dehumidifiers we tested all had major issues and flaws that keep us from recommending any one of them. The only viable alternative to the FFAD3033R1 in the size class is the dehumidifier it replaced, the Frigidaire FAD301NWD. But, as we discuss in our FFAD3033R1 review, the FAD301NWD itself has its own set of shortcomings that we find hard to overlook and that keep us from recommending it as a good alternative to the FFAD3033R1 in the size class. Thus, our only recommendation in the 30 pint size class for 2017 is the Frigidaire FFAD3033R1.

The Rest of the Rankings (Dehumidifiers We Do Not Recommend)

Below you’ll find the three other 30 pint dehumidifiers we’ve tested, listed in order of their overall composite score (shown in parentheses). This score is obtained from adding up each unit’s score (out of 5) in each respective review category.

#2 Hisense DH-35K1SJE5 (47)
#3 GE ADEL30LR (45)
#4 Haier DM32M-L (34.5)

Again, we do not recommend any one of these dehumidifiers for purchase.




2014 Buyer’s Guide

We’ve included our buyer’s guide for 2014 below for your reference. Despite the fact that many of the comments we make below have lost their relevance (due to new information and data we’ve obtained in recent testing), there may be bits and/or pieces of useful information you can still glean from them today.

We preface this buyer’s guide by noting that we’ve tested and reviewed only three 30 pint dehumidifiers so far. We note here that the three units we did review are not the three best rated units on the market. These three units are, however, readily available at your local brick and mortar retail store. We will be purchasing better rated 30 pint units to review and test in the coming months. Below we’ll discuss our findings and recommendations regarding the three units we have tested and hope to add more information to this page as we continue to review other 30 pint dehumidifiers on the market in the future.

The three 30 pint dehumidifiers we did test are the GE ADEL30LR, the Haier DM32M-L, and the Hisense DH-35K1SJE5. We preclude our discussion of these three units with a recommendation. Should you be interested in purchasing a smaller, lighter, less expensive dehumidifier a 30 pint unit may very well serve your purposes quite well. However, it is our recommendation that you strongly consider spending the extra $20 to $30 it would take to upgrade to at least a 50 pint unit. Most 30 pint dehumidifiers retail for around $160. For under (approx.) $200 you can purchase one of our top rated 50 pint units (the Frigidaire FAD504DWD retails for about $195) or even a top rated 70 pint unit (the Keystone KSTAD70B retails for about $190). We suggest you read either our 50 or 70 pint dehumidifier buyer’s guides for information on the best rated units in each size class.

Again, before we discuss the units we tested, we want to make it clear that the units we did review are not the best rated 30 pint dehumidifiers on the market. If you’re looking for a top rated small capacity unit consider the same brands that provided the top rated 50 and 70 pint units. We would recommend that you check out either the Frigidaire or Danby 30 pint units and carefully read over their respective consumer reviews. Although we haven’t tested them yet either the Frigidaire FAD301NWD or the Danby DDR30A2GP should be a great choice if you must buy a 30 pint unit. Frigidaire units were top rated in both our 50 and 70 pint dehumidifier reviews. The Danby DDR50A2GP was one of the best rated 50 pint units we tested.

With that being said, let’s take a brief look at the 30 pint dehumidifiers we did test. We will only take a quick glance, as these units are not recommended good buys in the 30 pint category. Let’s get to it.

Of the three units we did test, the Hisense and GE units were by far superior to the Haier 30 pint unit. The Haier was the worst performer in all but one of our four real world performance tests. It was the least energy efficient and took the longest time to dehumidify our test environment. The Haier was also the only dehumidifier we tested that features a mechanical knob to adjust the set humidity level. We discuss this unit’s few strengths and many weaknesses in detail in its review which you can read here.

The GE ADEL30LR is a much better option, although we noted in our review that it has received an unusually high number of negative (1 or 2 star) consumer reviews. The unit is quite portable, features three fan speeds instead of two (for greater adjustability), and was also the most quiet 30 pint dehumidifier we tested.

Finally, the Hisense DH-35K1SJE5 outperformed both the Haier and the GE in most of our real world performance tests. It removed moisture more quickly than both other units and it was also the most energy efficient 30 pint dehumidifier we tested. Of the three units we did test, we would recommend the Hisense over the GE and definitely over the Haier as the best option available should you have to buy a dehumidifier at a local brick and mortar store.


  1. Tracy says

    Thank you for this excellent and well-written summary of your research. I am looking to buy a dehumidifer for my 3 year old son’s room. Our 100 year old rental house does not feel excessively damp but in the winter in Pacific Northwest we get so much rain, and on hot summer days it can get very muggy in that room due to south facing heat absorption. My hygrometer now is at about 50% but I’d like that to be 40 or lower to inhibit dust mites. the room is about 15 x 15. Will the Frigidaire 30pint be too loud for continuous operation at night? Not sure how loud 45 decibels is…. Would it be useful to run it in the daytime and then turn off at night? would another style dehumidifier be more suitable but effective? thanks very much

      Whether the Frigidaire 30 pint is too loud for you to keep running overnight in your son’s room will depend on how light of a sleeper he is and whether he would be bothered by the fan “noise” the unit produces. By most people’s standards I’d say that the “noise” that this unit produces isn’t very loud and isn’t unpleasant either (because it’s only fan noise). Most people would be able to sleep with this unit operating in their room without issue.

      For the size room and specific application you described the 30 pint FFAD3033R1 should work fine.
