As of 2015, Target sells dehumidifiers made by Eva-Dry, Frigidaire, Haier and Sunpentown. The model rated highest by Target reviewers is the Sunpentown 60-Pint Energy Star Dehumidifier.
Dehumidifiers remove moisture by forcing room air over chilled coils. The moisture condenses on these coils and drips into a bucket that is then emptied by the user. Large dehumidifiers remove up to 75 pints of moisture a day, medium units remove up to 50 pints and small units remove 25 to 40 pints. In general, larger dehumidifiers are more energy efficient than smaller units. Dehumidifiers with the Energy Star seal are 10 to 20 percent more efficient than their counterparts.
