Dehumidifiers

What's behind our dehumidifier Ratings?

• Overall score
  Overall score is based mostly on water removal, response, efficiency, and noise. Displayed scores are rounded; models are listed in order of precise overall score.
• 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.
• Humidistat accuracy
  Humidistat accuracy is how closely humidistats came to keeping the humidity levels we set for them in our test chamber.
• Energy efficiency
  Energy efficiency measures kWh needed to remove a pint of water from the air; the fewer the kilowatts, the higher the score.
• 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.
• 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.
• Fan stays on
  Some models have fans that stay on even when the compressor turns off. The only time the fan stops is when the water collection bin fills up.
