One of the best humidifiers for damp areas.

When the temperature and humidity rise and the weather gets muggy, a dehumidifier is a good defense to keep mold and mildew at bay.

But the appliance can't solve all your problems: First, you need to address the sources of the moisture in your home.

“If a space repeatedly has standing water or a musty smell, even the best dehumidifier won’t fix the dampness problem on its own,” says John Banta, the engineer who oversees CR's dehumidifier tests.

Tackle underlying problems first, then run a good dehumidifier to help keep the humidity level between the ideal 30 and 50 percent—any higher, and mold and dust mites start to thrive.

 

More on Your Home's Environment

You'll see 36 models in our dehumidifier ratings from 16 brands, including Arctic King, Emerson, Frigidaire, GE, Hisense, HomeLabs, Honeywell, LG, and Toshiba. All earn an Excellent rating in our water-removal tests. That means they remove the amount of water from the air that their capacity's claim.

All dehumidifiers have a humidistat (like a thermostat for humidity), but some are more accurate than others. The humidistat detects the humidity level in an area, and cycles the dehumidifier on or off as needed to maintain the desired humidity level, similar to how your air conditioner holds the room at its set temperature.

Dehumidifiers that earn an Excellent rating in our humidistat-accuracy tests come very close to meeting the humidity level you select.

And then there's the noise—most of it comes from the fan. Dehumidifiers that garner an Excellent rating in our noise test are about as loud as a refrigerator running. The noisiest dehumidifiers? They make as much racket as a box fan set on the highest speed and earn only a Fair rating.

Changes in the Dehumidifier Aisle

Most dehumidifiers are labeled with capacities of 30, 50, or 70 pints, which refer to the amount of water the dehumidifier can remove from the air within 24 hours (you’ll see them divided into small-, medium- and large-capacity categories in our dehumidifier ratings.

But as you shop this summer, you might see dehumidifiers with 20-, 30-, or 45-pint capacities. The Department of Energy changed its test standard by lowering the room temperature to better reflect conditions in a basement, where dehumidifiers are typically used. Any dehumidifier made in the U.S. or imported as of June 13 must conform to the new test standard. 

“It doesn’t mean that these new dehumidifiers remove less water,” explains CR’s Banta. “It’s just that they were tested in conditions where less water was present in the air.” Cooler air contains less moisture, which is why the number of pints listed is lower.

As manufacturers sell out of 30-, 50-, and 70-pint models, retailers will begin to stock models measured against the new standard. We'll test these dehumidifiers when more become available in stores and online.

Below are six top-performing dehumidifiers to buy right now—with picks from each of the three current categories. Depending on your budget, you might consider a larger capacity than needed. The dehumidifier will dry your room faster, and you won't have to empty the tank as often.
