7 Best Dehumidifiers Consumer Reports 2019 – Top Rated

Full-size compressor based dehumidifiers (such as those in the photo above) are capable of removing upwards of 10 gallons of water from the air each day. Most thermo-electric and desiccant units can remove only a few ounces per day at best.

Compressor based units can be used to dehumidify any (reasonably) sized space at any humidity level. Most thermo-electric and desiccant units can only be used to dehumidify small spaces (like a closet, for example) and only if the humidity level in that space isn’t very high.

Because thermo-electric and desiccant units simply will not work for most people in most situations we’re not going to talk about them in this guide (for information on these dehumidifiers see our thermo-electric and desiccant dehumidifier guides).

A Critical Step Before You Buy

We’ll get to our top dehumidifier picks (our recommendations of the best dehumidifiers) in just a moment, but before we do, it’s necessary that we first go over a very important concept – dehumidifier capacity.
A clear understanding of this concept will be absolutely critical for you to determine exactly which model dehumidifier you need to buy.

We mentioned earlier that compressor based dehumidifiers are capable of removing upwards of 10 gallons of water from the air per day. But not all of them can remove a whole 10 gallons. Some can only remove about 6 gallons per day, others only 4 gallons per day.

What Capacity Dehumidifier Should You Buy?

At this point in most other dehumidifier buyer’s guides, the author of the guide would point you to a size chart to help you determine what capacity dehumidifier you need to buy. The most popular of such sizing charts is the one given by AHAM, the Association of Home Appliance Manufacturers. AHAM tests and verifies the moisture removal rate and energy efficiency of most dehumidifiers sold in the United States (note that they don’t actually review and compare dehumidifiers; they just verify manufacturer claims).

Why do we disagree with the use of this chart? See the 8 reasons below.

1. The chart cannot actually be found anywhere on AHAM’s official website or AHAM’s official test specification website. Even though a number of different consumer publications reference the chart above and give the source as AHAM, the fact that AHAM is indeed the source cannot be verified because the chart, as it has been reproduced by those same publications, doesn’t actually exist anywhere on any of AHAM’s websites.

2. Only two of the capacities listed in the chart – 32 in the second and third row and 30 in the bottom row – correspond to actual capacities of dehumidifiers you can buy in stores. Reading the top row of the table, there are no 10, 14, 18, 22, or 26-pint dehumidifiers readily available for purchase anywhere online or in stores.

3. The chart has a limited range. It begins at 500 square feet and ends at 2500 square feet. What if the space you need to dehumidify is smaller than 500 square feet? What if it’s larger than 2500 square feet? The chart fails to make recommendations for spaces that fall outside of the given range.

4. The chart fails to take into account the height of the space you need to dehumidify. Rooms with higher ceilings contain more air than rooms with lower ceilings – something that the chart above doesn’t take into account at all. Much more appropriate would be recommendations based on the volume (measured in cubic feet ), not the area of the space you need to dehumidify.

5. The chart fails to take into account dehumidifier CFM – the CFM of the dehumidifier’s intake fan (the Cubic Feet of air the fan pulls into the dehumidifier every Minute). We rate dehumidifiers with higher CFM fans much higher than those with lower CFM fans. Why? Because only half the battle in dehumidifying a given volume of air involves the process of actually removing moisture from it inside of the dehumidifier. The other half involves pulling that air into the dehumidifier for it to be dehumidified. A higher CFM fan is able to pull more air from greater distances surrounding the dehumidifier. This is especially important if you want to dehumidify a large space.

6. The chart is likely based on an extrapolation of test data obtained in a highly controlled environment. It’s likely not based on actual experiments in environments corresponding to the actual conditions (moderately damp, very damp, wet, extremely wet) it makes recommendations for.

How can a dehumidifier manufacturer make the claim that their 70-pint dehumidifier can actually remove 70 pints of moisture per day? The manufacturer does so by voluntarily sending it to AHAM for testing. AHAM then measures the dehumidifier’s moisture removal rate in a laboratory that is set to exactly 60% relative humidity (RH) and 80º F.

7. The chart contradicts manufacturer recommendations. See this Friedrich dehumidifier brochure, for example. It recommends that a 70-pint dehumidifier be used for a 1,000 to 2,000 sq. ft. “wet” or “extremely wet” space which contradicts the 20 points to the 37-pint recommendation of the size chart above for the same size space under exactly the same conditions.

8. The chart contradicts our own research and testing. Take, for example, the chart’s recommendation that a 44-pint dehumidifier is used for a 2,500 sq. ft. “extremely wet” space. Our own experiences with all of the dehumidifiers we’ve tested so far lead us to believe that a 44-pint dehumidifier (which doesn’t actually exist, but that’s beside the point here) is not nearly of a large enough capacity to dehumidify such a large space under those conditions.
