Friedrich D70BPA

This 70-pint dehumidifier comes with a defrost setting, as well as a pump, so that the moisture it collects can be emptied out a window. Read More

Pros

  • Can be used in colder climates
  • pump allows moisture to be drained out a window

Cons

  • Nothing to dislike

A dehumidifier's primary task is just what it sounds like: to remove moisture and humidity from the air. It's the opposite of a humidifier, which adds moisture. Dehumidifiers aren't just great at taking the edge off hot, humid summer days. They're also excellent at combatting mildew in areas with a persistently muggy climate, or after a major leak or flood. Keeping your home's humidity levels under control can reduce the likelihood of mold growth, bugs that thrive in moist climates, and odors in general. An added bonus is that many you buy can do so while still fitting into a small space.

These are our recommendations for the best dehumidifiers on Amazon.

What You Should Know About Dehumidifiers

An electric dehumidifier works in a very similar fashion to an air conditioner. Inside of a dehumidifier, you'll find a number of components: an evaporator, a compressor, and a condenser. As the warm, humid air in your home passes over the winding, tubular surface of the evaporator, refrigerant chemicals inside the tubes absorb the heat in the air. As a result, the air's temperature cools. As the air chills, the moisture in the air transforms into liquid water, which collects on the evaporator. This water drips off of the evaporator and is collected into a container to be disposed of.

As it absorbs the heat from the outside air, the refrigerant inside of the evaporator is heated. This increase in temperature transforms from a liquid to a gas. The vaporized refrigerant is sucked into the dehumidifier's compressor. Here, the refrigerant is, well, compressed, raising both the amount of pressure it's under and its temperature. The resulting hot, pressurized gas is then forced into the condenser, where it's transformed back into a liquid state as the heat in the refrigerant is radiated away. Unlike the condenser on an air conditioner, which is designed to channel warm air out of your home, the condenser on a dehumidifier keeps the heat inside of your home. Once the liquid refrigerant has been cooled in the condenser, it's recirculated back into the evaporator, where the whole process starts all over again.

Not all dehumidifiers use this method to pull humidity out of the environment around them. Some use silica gel, formed into beads, to collect moisture from the air. Moisture is absorbed into pores on the surface of the silica, leaving the air that carried the moisture dry as a bone. There are limits to how much moisture silica gel can absorb. Once the gel has reached its limits, heating it at a high temperature, either in an oven or through the use of an electric heating element, will dry the moisture out of it, leaving the material ready to take on more water.

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—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 other 70-pint dehumidifiers, but it looks sleek, is easy to use, and has deep handholds and wheels for easy moving and storage. With an easily accessible air filter and an auto-defrost function that's ideal for operating in cold temperatures, the LG Puricare will rid your home of humid air in no time.

Pros

  • Quickly deals with humidity

  • Low power use for a unit of its size

  • Easy to move

Cons

  • Nothing to dislike

Hisense DH70K1G

The Hisense easily earned its place in the rankings with its solid performance and respectable price. Often cheaper than most other models at this capacity, the Hisense was able to reduce the air humidity by an 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 handholds 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's easily accessible, and the buttons and text on the control panel are highly visible.

Pros

  • Solid performance at a respectable price

Cons

  • Lack of handholds makes it more difficult to move around your home

Eva-Dry E-500

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 an 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 to 14 hours while the moisture is evaporated away, causing the beads to return to their original orange color. The Eva-Dry isn't 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.

Pros

  • Compact

  • Requires no power to use

  • ideal for use in tight spaces

Cons

  • Can only absorb six to eight ounces of moisture at a time

  • Not useful for removing a large amount of humidity from a room, quickly

Product image of Frigidaire FGAC7044U1
Frigidaire FGAC7044U1

Of all of the 70-pint dehumidifiers we tested, Frigidaire's model 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 handholds, the Frigidaire is easy to move and store. However, the filter is hidden, accessible only after removing the water bucket. On the other hand, the unit 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.

Pros

  • Controllable via WiFi

  • Easy to move and store

Cons

  • Filter can only be removed after removing the dehumidifier's reservoir

Friedrich D70BPA

In the course of an hour and 50 minutes, the Friedrich model we tested was able to reduce the relative humidity by about 46%. In addition to solid performance with respect to moisture removal, the Friedrich also has both a defrost setting (for use in colder climates) and an internal pump that allows for water removal through windows or other methods of drainage that are up higher than the dehumidifier itself. The wheels and the large handholds also make it a cinch to move.

Pros

  • Can be used in colder climates

  • pump allows moisture to be drained out a window

Cons

  • Nothing to dislike
