These dehumidifiers were incredibly quiet in our tests and also scored well for keeping rooms comfortable.
By Consumer Reports
To recommend the quietest dehumidifiers below, we turn to our test labs, where Consumer Reports engineers measure the decibels of every dehumidifier they test.
The loudest dehumidifier in our tests gets a fair rating, meaning it’s about as loud as a box fan on the highest setting. But most are quieter than that, scoring Very Good (about as loud as a normal conversation) or Excellent (like a fridge buzzing).
To test dehumidifier decibels, we crank each model to its highest fan and humidity removal settings. Then our testers place a decibel meter on a tripod 2 feet in front of the dehumidifier and 3 feet off the floor, simulating the sound of the dehumidifier if you’re sitting in a room on.
Below are nine incredibly quiet dehumidifiers. They are organized by capacity, or the amount of water they can remove from the air. To learn more about these and other dehumidifiers we’ve tested, check out our full dehumidifier ratings and read the CR dehumidifier buying guide. If you’re looking to dry out a damp area, check out our dehumidifier recommendations for basements and crawl spaces. And once you’ve found the model that suits your needs, here’s how to get the most out of your dehumidifier.
Quietest Large Capacity Dehumidifiers
CR’s opinion: For a large humid space, buy the largest capacity unit you can afford. The Honeywell TP70WKN is a large capacity dehumidifier that can extract 50 pints of water from the air per day by current Department of Energy standards. Its limited reservoir (13 pints by our measurement) means you’ll have to empty it frequently, but at least it shuts off automatically when full. It scores very well in our noise test; it’s about as loud as a normal conversation. Features include a timer, digital display and auto-restart, which comes in handy in the event of a power outage or brownout. But the brand earned average ratings of Good for predicted reliability and owner satisfaction in CR member surveys.
CR’s opinion: The Midea MAD50C1ZWS checks all the key boxes to keep your basement dry. Water elimination: excellent. Accuracy of the humidistat: also excellent. Sound and energy efficiency: Very good. Indeed, its only notable downside is that it has a relatively small 15-quart tank, which contributes to its poor convenience score. To remove the 50 pints it’s designed to handle daily, you’ll need to empty it several times a day, or purchase and attach a hose to divert the water to a drain. Predicted reliability, however, received an excellent rating in our member survey; owner satisfaction earned it a good lukewarm rating.
CR’s take: The hOmeLabs HME020031N quietly, efficiently, and reliably removes up to 50 pints of moisture from your air per day. We give it a very good rating for noise and an excellent rating for water drainage. Its humidistat gets a very good accuracy rating and it is very energy efficient. It’s not practical, however; its relatively small 12-quart tank will require frequent emptying unless placed near a drain. The brand received an excellent score for predicted reliability in our member survey and a very good score for owner satisfaction.
Quietest mid-capacity dehumidifiers
CR’s opinion: Medium capacity dehumidifiers are for a medium or large sized room that is a little humid but not wet. The mid-capacity Midea MAD35S1QWT is the highest rated model in all of our dehumidifier ratings. This high-performance unit, which can remove 35 pints of moisture from the air per day, scores top marks for noise, making it one of the quietest in its class. It also passes our tests for water disposal, energy efficiency and convenience. This model is equipped with a digital display, an integrated water pump, an automatic restart function and a timer.
CR’s opinion: Capable of removing approximately 35 pints of water from the air per day, the mid-capacity hOmeLabs HME020006N is one of the quietest in its class, earning an excellent rating in our noise test. There’s a filter cleaning timer and alert, and like most models we tested, it has an auto-restart feature. In our member surveys, hOmeLabs received an excellent rating for predicted reliability, which speaks volumes about its long-term use, and a very high rating for owner satisfaction.
Quietest small capacity dehumidifiers
CR’s opinion: Our top rated small capacity dehumidifier is the Midea MAD20S1QWT. This model scores top marks for water removal, noise, convenience, and humidistat accuracy in CR lab tests. It’s also energy efficient, comes with a drain hose, and has a timer and an auto-restart feature that returns the machine to its previous settings after a power outage.
CR’s opinion: The TCL TDW20E20 is an affordable, high performance, small capacity dehumidifier with the ability to remove 20 pints of moisture per day. Well-suited for drying out small spaces, it gets a very good score in our noise test and an excellent score for water evacuation. It comes with the ability to auto-restart and has top-notch power efficiency, but lacks built-in cord storage. TCL is a new brand in our testing, so we don’t have long-term feedback on customer satisfaction or reliability yet.
CR’s opinion: The Frigidaire FFAD2233W1 scores very high in our noise test, and it gets our highest marks for convenience, energy efficiency, and water disposal, eliminating 22 pints of moisture per day from the air. This dehumidifier’s water tank holds nearly 12 pints of water, so you won’t need to empty it as often as other small-capacity models we’ve tested. But our testers found that the accuracy of the humidistat struggled to precisely match the desired humidity level we set.
CR’s opinion: The hOmeLabs HME020030N Small Capacity Dehumidifier gets a very good rating for noise in our ratings and an excellent rating for water removal. Its humidistat accuracy is also top-notch, so you can set it and forget it, knowing it will achieve your desired humidity level. However, it’s not particularly energy efficient; Plus, its small 7-quart reservoir means you’ll need to empty it frequently. Notably, hOmeLabs dehumidifiers scored highly in our member survey for predicted reliability and a very high score for owner satisfaction.
