I like this 22-pint dehumidifier for homes up to 3000 square feet with a 1.45-gallon water tank, reusable air filter, quiet 50dB operation, and auto shut-off.I found the controls clear and easy to read. The interface is intuitive, with obvious up/down buttons and fan icons to indicate speed settings. Setting the humidity level is simple because the display continuously shows the current room humidity. Like a thermostat, I can just select a lower target percentage and the unit automatically maintains it. I greatly prefer this over an arbitrary low/medium/high dial because setting an exact humidity percentage is more precise, easier to duplicate year-round, and potentially more energy efficient. The controls are conveniently located on the flat top of the unit, so I do not need to bend down or kneel to read a low front-facing display.My application is a basement utility room. Starting at 44% humidity, the unit reduced the room to 40% in about 3.5 hours. It also did not noticeably heat up the roughly 100-square-foot room while operating, which I take as a good sign of efficiency. In my setup, the room has a door to isolate noise from the well pumps and hot water heater, but airflow continues through a large vent above the door, so the dehumidifier is effectively exchanging air with about a 500-square-foot area.The unit also includes several advanced features, including a continuous-run mode that would be useful for drying a damp basement or helping dry carpets after a spill. There is a fine mesh filter built into the case that can easily be removed and washed. I appreciate that it uses a reusable permanent filter rather than disposable filters that require regular replacement. The unit also includes a gravity drain connection on the back for attaching a hose to continuously drain water into a lower floor drain or sump. My model does not include the optional powered pump, though the manual indicates pump-equipped versions are available.The unit is ENERGY STAR certified for energy efficiency, helping reduce operating costs. The label on the unit lists an IEF rating of 1.7 liters per kWh, which appears quite efficient for this size category.Overall, I found this to be a quiet, compact, and efficient dehumidifier that looks good, is easy to operate, and performs well.
