Auto defrost and a child lock are the two features that let this unit sit in a basement or a family hallway and be left alone. It removes up to 52 pints of water a day at 95 degrees Fahrenheit and 90 percent relative humidity across spaces as large as 4500 square feet, holding humidity anywhere from 30 to 80 percent. Three working modes cover dehumidifying, drying clothes and continuous operation, with two fan speeds behind them. Rated power is 350 watts at 120V, with input measured at 174 watts in normal running. Water leaves either by emptying the 0.66-gallon tank or through the included 3.3-foot hose, and a water-full shutoff stops overflow. The cabinet measures 12.5 inches wide, 9 inches deep and 19 inches tall and weighs 32 pounds.
