Our Top Dehumidifier Picks

In the same way that humidifiers offer relief from dry air and mucus in the winter months, dehumidifiers keep away mold, mildew and dust mites, especially in spring and summer when the weather is generally wetter. Basements and bathrooms are the worst offenders of trapping humidity and moisture. If you notice condensation on windows, a musty smell, or that surfaces or the air feel damp, then it's worth trying a dehumidifier to alleviate these issues. Just know, though, that a dehumidifier won't fix underlying moisture issues from water leaks or poorly sealed cracks.

How to Choose a Dehumidifier

For our tests, we focused on ease of use, noise level and tank size. When choosing a dehumidifier for your home, the most important factor to consider is the size of the space in which you'll use the dehumidifier. Most homes won't require anything bigger than a 35-pint tank. However, if you live in an older home, need serious help removing moisture from an unfinished space, like a garage, or want to go longer between emptying the tank, then a larger tank size is ideal. Generally, the cost increases with the tank capacity.

Important Features to Consider

Additional features like filter cleaning/replacement indicators, full tank alerts, fan settings, timers and auto defrost usually come standard. We tested a few models with Wi-Fi and found that this feature, while very convenient, isn't necessary or worth the extra cost for most situations. However, if you want to use a dehumidifier in a remote room, like a basement with an exterior entrance or a detached garage, then a Wi-Fi-enabled app would come in handy for getting updates on the humidity and water tank fill levels. Since dehumidifiers typically run for extended periods of time, make sure you purchase one with Energy Star certification for the highest efficiency.

Using a Dehumidifier

Depending on your preference and setup, you can either manually remove the tank when it reaches capacity, attach a hose to the tank for continuous, hands-off drainage or purchase a dehumidifier with a built-in pump to automatically dump water into a drain or sink. We like emptying the reservoir into a watering can to water plants.

And if you're worried about the air getting too dry, rest assured that a majority of dehumidifiers, including the ones we recommend, will not keep running once your desired humidity level is reached. The EPA recommends keeping humidity levels below 60 percent. Those with dry sinuses and humidity-loving houseplants should pass on a dehumidifier.

Keeping in mind price, reviews and performance, we picked the following dehumidifiers as the best buys. Check out our recommendations below.
