Dehumidifier Size Calculator
Find the dehumidifier capacity, in pints per day, that a damp or water-damaged space needs based on its size and how wet it is.
Dehumidifiers are rated by how many pints of water they pull from the air in a day. A space that is just musty needs far less capacity than one with standing-water seepage. Pick the area and dampness level for a recommended capacity. For active flood restoration, professionals also use a rough rule of about one commercial low-grain-refrigerant unit per 1,000 sq ft, which the result notes.

General guidance, not a precise specification. Capacity uses consumer pint ratings and scales with area. Heavily contaminated or actively flooded structures should be assessed by a restoration professional.
