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: Digital display, Frost control, Tank size (pts.), Claimed pts/day, Alert for filter cleaning, Auto re-start and Timer.

ratingsBest Dehumidifier for Water removal
product image

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: Digital display, Frost control, Tank size (pts.), Claimed pts/day, Alert for filter cleaning, Auto re-start and Timer.

ratingsBest Dehumidifier for Noise
