A high-efficiency compressor system does the work here, and compressor dehumidifiers are the type that keeps performing in a cold damp space where desiccant units fade. This one removes 80 pints, or 38 liters, of water per day measured at 95 degrees Fahrenheit and 35 degrees Celsius at 90 percent relative humidity, and covers a maximum area of 4000 square feet. Humidity is set between 30 and 80 percent in auto mode, which then holds the room at that level, while continuous mode runs steadily without a target. High and low wind speeds match output to conditions. Water leaves two ways. The 1-gallon tank has a visible water level so it can be emptied by hand before it fills, or the drain plug takes the supplied 2-foot hose for continuous drainage that runs unattended. Everything is set from an intuitive control panel with an LED display, and a memory function restores the previous working settings after power is cut, so nothing has to be redialed. Inside drying and auto defrost keep running stable in cold conditions and leave the interior dry after use. A child lock adds family-friendly safety, and the removable and washable mesh filter keeps upkeep to a rinse. Noise stays at 42 decibels with a 24-hour timer, which is what makes it usable overnight. The 28-pound ABS, copper and aluminum unit measures 13.5 by 10 by 20 inches, moves on a top handle and 4 universal wheels, has a cable storage area to keep it neat after use, draws 250W at 115V 60Hz and 3.5A, and has a 6-foot power cord.
