The Eva-Dry Electric Petite Dehumidifier uses Peltier technology for economical, quiet operation. It is perfect for bathrooms and other small spaces where dampness and humidity are a problem. This unit is small enough to easily fit on your counter top, boat, or RV. Using only a fan and two aluminum plates to dehumidify, the unit will draw humid air over the warm plate and heat up the air. Once heated, it moves the air over the cool plate which draws the condensation and traps it in the removable reservoir. This dehumidifier unit absorbs 8 ounces of moisture in a 24-hour period. 6"L x 4.5"W x 8.5"H.
