  • Water removal
  • Humidistat accuracy
  • Cool room performance
  • Energy efficiency
  • Noise

Below lists the Dehumidifiers that rated best in each of the tests our experts looked for. Learn about how these tests were performed and find out which Dehumidifier is rated best when you subscribe.

Consumer Reports Ratings for Best Dehumidifiers

Best Dehumidifier for Water removal

Water removal measures pints per day removed under 80º F and 60 percent relative humidity as well as 70º F and 70 percent relative humidity. Models closest to claimed removal scored higher.


This Dehumidifier which tested best for Water removal has the following features: Tank size (pts.), Claimed pts/day, Digital display, Frost control, Auto re-start, Alert for filter cleaning and Timer.

Best Dehumidifier for Humidistat accuracy

Humidistat accuracy is how closely humidistats came to keeping the humidity levels we set for them in our test chamber.


This Dehumidifier which tested best for Humidistat accuracy has the following features: Tank size (pts.), Claimed pts/day, Digital display, Frost control and Auto re-start.

Best Dehumidifier for Cool room performance

Cool room performance measures pints of water removed and watts needed to remove this water when the dehumidifier is used in a room that is 50 degrees F and 60% relative humidity.


This Dehumidifier which tested best for Cool room performance has the following features: Tank size (pts.), Claimed pts/day, Digital display, Frost control, Auto re-start, Alert for filter cleaning and Timer.

Best Dehumidifier for Energy efficiency

Energy efficiency measures kWh needed to remove a pint of water from the air; the fewer the kilowatts, the higher the score.


This Dehumidifier which tested best for Energy efficiency has the following features: Tank size (pts.), Claimed pts/day, Digital display, Frost control, Auto re-start, Alert for filter cleaning and Timer.

Best Dehumidifier for Noise

Noise denotes loudness at the highest setting, measured in decibels. We also measured ability to run on low voltage and restart after a simulated blackout; models that didn't automatically restart are footnoted.


This Dehumidifier which tested best for Noise has the following features: Tank size (pts.), Claimed pts/day, Digital display, Frost control, Auto re-start, Alert for filter cleaning and Timer.
