Best Dehumidifier for a Basement
Most basements need a 50-pint dehumidifier. For basements without a floor drain, get one with a built-in pump. The GE 50-Pint with Pump ($280) is the top pick for pump drainage, while the Midea Cube 50 ($260) is best overall with its massive 4.2-gallon tank.

Understanding Your Needs
Basements trap moisture because they sit below grade, where groundwater seepage, poor ventilation, and cool concrete surfaces create ideal conditions for condensation. A dehumidifier rated at 50 pints per day (DOE 2020 standard) handles finished basements up to about 1,500 sq ft with moderate dampness. If your basement smells musty, shows condensation on pipes, or feels clammy in summer, a 50-pint unit is the right call. For very large basements over 1,500 sq ft or those with active water intrusion, step up to a 70-pint unit or consider a dedicated crawl space dehumidifier.
Why These Picks
The GE 50-Pint with Pump earns the top spot because most basements lack a convenient floor drain. Its built-in pump pushes water up to 16 feet vertically to a sink, window, or any drain point. Set it up once and forget about it. If your basement does have a floor drain, the Midea Cube 50 is the better choice: its 4.2-gallon tank is 3x larger than competitors, and it runs at just 47 dB.

Sizing Note
Basements get a 1.3x sizing modifier in our calculator because below-grade spaces retain more moisture than above-ground rooms of the same size.
