What Size Dehumidifier for a Basement?

Side-by-side cutaway diagram of a crawl space in July. On the left, a vented crawl space: outdoor air at 85F and 75 percent humidity, with a dew point of 76F, enters through an open vent. Because the ground keeps crawl space surfaces at 68F, below that dew point, moisture condenses onto the joists and the bare soil and the space ends up at 90 to 100 percent humidity. On the right, a sealed crawl space on the same day: the vents are sealed, a vapor barrier covers the soil, and a crawl space dehumidifier holds the air at 52 percent humidity, so nothing reaches its dew point and the space stays at 50 to 55 percent.

Cutaway diagram of a dehumidifier. Humid room air at 78F and 70 percent humidity is drawn through a filter and over a cold coil at around 40F, where the moisture condenses and drips into a bucket or drain hose. The dried air then passes over the hot coil, which reheats it, and a fan blows it back into the room at 82F and 45 percent humidity. A compressor and refrigerant loop connect the two coils.

Diagram of three dehumidifier drainage options. First, the bucket, which the unit shuts off when full and which a 50-pint unit fills twice a day in a damp basement. Second, a gravity drain hose running from a raised unit down to a floor drain, which must fall along its whole length. Third, a built-in pump that pushes water upward through a thin tube to a sink or window when there is no drain below.

Heat map showing the dehumidifier capacity needed in pints per day by floor area and dampness. For a moderately damp space at 50 to 60 percent humidity: 20 pints at 500 square feet rising to 40 pints at 2,500 square feet. For a very damp space at 60 to 70 percent: 25 pints rising to 50. For a wet space at 70 to 85 percent: 30 pints rising to 55. For an extremely wet space above 85 percent: 35 pints rising to 60. Add 10 pints for a below-grade basement.
