The Best Dehumidifiers of 2018

By Jonathan Chan, Kyle Hamilton, and Julia MacDougall

If you're consistently dealing with clean-up from a major leak or flood, mildew, or just the gross feeling of a humid day, then you're probably in the market for a dehumidifier. A dehumidifier's primary task is just what it sounds like—the opposite of a humidifier—to remove moisture and humidity from the air.

Removing moisture from the air can increase your room's air quality by reducing the likelihood of mold growth, bugs that like humid climates, and odors in general.

Our top pick, the LG Puricare UD701KOG (available at Amazon), removed a lot of humidity in short time span, without blowing up the electric meter. In our temperature- and humidity-controlled test lab, we tested 12 dehumidifiers to see which models can get the job done and which ones will leave you high and not-dry.

These are our picks, in order:

  1. LG Puricare UD701KOG

LG Puricare UD701KOG

Best Overall

Capacity: 70 pints

Pump? No

Range of humidity settings: 30%-80% RH, continuous

In our tests, the LG Puricare dehumidifier was able to reduce the humidity in our test lab by about 45% in a little more than 90 minutes, which is no joke. On top of that, this dehumidifier had the lowest energy usage of the 70 pint models we tested by a wide margin. While dehumidifiers are unobtrusive, and are the epitome of the "set it and forget it" mindset, there are definitely times where more rapid humidity removal is better, and this LG is the best horse in that race.

The Puricare is noticeably taller than the rest of the 70 pint dehumidifiers (with a height about 2" taller than the usual 24" height of the other dehumidifiers), but it looks sleek, is easy to use, and has deep hand-holds and wheels for easy moving and storage. With an easily accessible air filter and an auto defrost function that is ideal for operating in cold temperatures, the LG Puricare UD701KOG will rid your home of humid air in no time.

Hisense DH70K1G

Best Value

Capacity: 70 pints

Pump? No

Pump Model available: Yes

Range of humidity settings: 30%-80% RH

The Hisense DH70K1G easily earned its place in the rankings with its solid performance and very respectable price. Often priced at $50-$100 cheaper than most other models at this capacity, the Hisense was able to reduce the air humidity by amount similar to that of the LG Puricare, but over a slightly longer time period and using slightly more energy.

While this model doesn't have hand holds on the sides, it does have a big handle on top, so it can still be lugged up or down flights of stairs. The filter is easily accessible, and the buttons and text on the control panel are highly visible.

  • Editors' Choice

Eva-Dry E-500

Best Portable

Capacity: 6-8 oz

Pump? No

Range of humidity settings: N/A

Of the three smaller models we tested, the Eva-Dry E-500 removed the most moisture from the air, reducing the relative humidity by about 19% in about 1 hour and 40 minutes. The E-500 is especially portable because it doesn't require power to operate; it uses desiccant silica beads (like those silica packets that sometimes come with things you've just bought) that passively absorb moisture.

Unlike entirely non-electric dehumidifiers, the Eva-Dry does use electricity sometimes. Once the orange beads are full of moisture, they turn green. To refresh the beads, you need to plug it into an outlet and wait for 10-14 hours as the moisture is evaporated away, causing the beads to return to their original orange color.

The Eva-Dry E-500 is not meant to be used in situations where you need to remove moisture immediately; we recommend you use the E-500 for low-key, constant moisture removal, such as on boats or in RVs.

What to look for in a dehumidifier

Dehumidifiers draw in warm, moist hair and then use coolants and fans to remove moisture from the air before pumping it back out again. Once all that water—or condensate— is removed it has to go somewhere, and that will probably be your biggest factor in deciding what kind of dehumidifier to buy. For electric dehumidifiers, there are three main types of water collection:

Bucket: These are the simplest, but they'll shut off when the bucket is full to prevent overfilling. You also have to dump them manually, so it may not be the best choice for hard-to-access or high-humidity places.

Continuous drainage: Sometimes called a "gravity drain," this is simply a hose that sticks out the back of the dehumidifier. To empty, you'll need a drain that is lower than the height of the spigot on the dehumidifier (otherwise the water will have nowhere to go). This is a great option for a room with a floor drain. If you don't have one, you'll need a built-in pump. Alternately, with a little elbow grease you can save money and connect it to an inexpensive condensate pump which will pump the water up to 20 feet away.

Built-in pump: If you need to continuously remove water and you don't have a conveniently-placed floor drain, you'll need to pump that water up and away. Some premium dehumidifiers include a built-in pump, but you'll likely pay for the privilege.

Continuous drainage versus bucket humidifiers

Once it's removed from the air, all that water needs to be dumped somewhere. Two options are continuous drainage (left) or a simple bucket (right). Bigger dehumidifiers tend to have multiple options.


Other dehumidifiers we tested

Frigidaire FFAD7033R1

012505279645

Frigidaire FFAD7033R1

Capacity: 70 pints

Pump? No

Pump Model available: Yes

Range of humidity settings: 35%-85% RH, continuous

It's not surprising that the Frigidaire FFAD7033R1 is one of the most popular dehumidifiers on the market. This no-nonsense dehumidifier managed to reduce the relative humidity by about 50% in about an hour and 40 minutes.

While it doesn't have hand-holds, the FFAD7033R1 has a large handle and wheels that allow it to move easily. The filter is mounted on the back of the dehumidifier, and is easy to remove and clean as needed. The Frigidaire FFAD7033R1 is a great workhorse dehumidifier.

Ivation IVADM10

840102105353

Ivation IVADM10

Capacity: 20 oz

Pump? No

Range of humidity settings: on/off

The Ivation IVADM10 is a more portable dehumidifier that is great for those that need active moisture removal in smaller spaces. It was able to reduce the relative humidity in our test lab by about 15% in an hour and a half.

Unlike larger options, there is no option for hose drainage. The water tank is your only option. But it's easily removable and so small it can be emptied with one hand. The lightweight, compact design means that it's easily stored or moved from room to room.

Honeywell DH70W

848987001418

Honeywell DH70W

Capacity: 70 pints

Pump? No

Pump Model available: Yes

Range of humidity settings: 30%-90% RH

The Honeywell DH70W performed almost identically to the Frigidaire FFAD7033R1, but it required a higher energy usage to accomplish that feat.

The control panel is both intuitive and easily visible, but the neatest feature of the Honeywell DH70W is its pop-up filter air filter, which makes maintenance a breeze.

1byone 705US-0001

6970323130996

1byone 705US-0001

Capacity: 14 oz

Pump? No

Range of humidity settings: on/off

The 1byone 705US-0001 is the last of the three smaller dehumidifiers we tested. It was able to reduce the humidity in the test lab by about 16% in just under two hours.

The design of the 1byone is similar to that of the Ivation, in that it is best for smaller rooms, easy to move, easy to store, and easy to operate. There is no hose drainage, just the bucket.

Frigidaire FGAC7044U1

012505282461

Frigidaire FGAC7044U1

Capacity: 70 pints

Pump? No

Range of humidity settings: 35%-85% RH, continuous

Of all of the 70 pint dehumidifiers we tested, the Frigidaire FGAC7044U1 removed the most moisture from the air: in nearly two hours, it reduced the humidity in the room by about 54%.

With a handle, wheels, and hand holds, this Frigidaire dehumidifier is easy to move and store. However, the filter is hidden and is only accessible after removing the water bucket.

On the other hand, the FGAC7044U1 is also "smart" and can be controlled over Wi-Fi through the Frigidaire app (iOS, Android); this functionality is a really great way to start removing moisture, even when you're away from your home.

Honeywell DH70PW

848987001579

Honeywell DH70PW

Capacity: 70 pints

Pump? Yes

Range of humidity settings: 30%-90% RH

The Honeywell DH70PW is almost identical to the DH70W, except that this version has an internal pump. The DH70PW was able to reduce the humidity by about 45% in just under two hours' time.

With sturdy hand holds and wheels, this Honeywell dehumidifier is easily moved and stored. The addition of an internal pump is a huge boon for disasters that require major moisture removal.

Kenmore KM70

8809154398153

Kenmore KM70

Capacity: 70 pints

Pump? No

Range of humidity settings: 35%-70% RH, continuous

Of the high capacity dehumidifiers we tested, the Kenmore KM70 pulled an impressive amount of moisture out of the air: the relative humidity in the test lab was reduced by about 53% in a time duration just shy of two hours.

Even though the filter is hidden and can only be removed once the water tank is removed, this dehumidifier has wheels and huge hand grips, making it easy to maneuver it across or between floors.

Friedrich D70BPA

D70bpa

Friedrich D70BPA

Capacity: 70 pints

Pump? Yes

Range of humidity settings: 30%-80% RH

In the course of 1 hour and 50 minutes, the Friedrich D70BPA was able to reduce the relative humidity by about 46%.

In addition to solid performance with respect to moisture removal, the D70BPA also has both a defrost setting (for use in colder climates) and an internal pump that allows for water removal through other windows or other methods of drainage that are up higher than the dehumidifier itself. The wheels and the large hand holds make the D70BPA a cinch to move.

GE APEL70LW

084691824077

GE APEL70LW

Capacity: 70 pints

Pump? Yes

Range of humidity settings: 35%-80% RH, continuous

In about 1 hour and 45 minutes, the GE APEL70LW reduced the humidity in the test lab by about 26%.

Like the Friedrich D70BPA, the GE APEL70LW has both defrosting and internal pumping functionalities. While the filter is difficult to access, the large hand holds are easy to grip and mean that you won't topple over lugging this down your basement stairs.

How We Tested

Who are we?

Hi, I'm Julia MacDougall, the Senior Scientist here at Reviewed. I've tested hundreds of products and overseen the testing of thousands more. Additional testing was performed by our lab techs Jon Chan and Kyle Hamilton.

The tests

We tested all the dehumidifiers in our custom-built, 17" x 12" test lab. It has highly accurate climate control, making an ideal place to find out whether these things do what they claim. We use this same room for testing refrigerators, freezers, and humidifiers.

Using four humidifiers (leftover from the humidifier roundup), we raised the room's relative humidity to 100%. Once there, the humidifiers were turned off, and the dehumidifier was turned on, with its maximum humidity removal and fan settings applied. Each dehumidifier ran for two hours. At the end of the two hours, we looked at the data from the monitoring system and four data loggers that capture both temperature and humidity data.

Dehumidifiers were judged on the relative reduction of the relative humidity (i.e the minimum humidity achieved subtracted from the maximum humidity of the room once the dehumidifier was turned on), the time it took to reach that minimum humidity value, and the energy usage. Some subjective aspects, such as filter accessibility, were also incorporated into the rankings.
