How we match
ClariSelect mathWe list the models whose makers rate them for at least your area, smallest first, with their pints per day under the current DOE test (65°F and 60% relative humidity). Wetter spaces call for a model rated well above your area.
LimitsOlder 80°F ratings read about a third higher for the same unit, so compare pints only between current ratings.
Questions
What size dehumidifier for a 1,000 sq ft basement?
A model its maker rates for 1,000 sq ft or more; if the basement is wet rather than just musty, go well above that and use continuous drainage.
Should a dehumidifier run all the time?
Set it to 45 to 50 percent and let its humidistat cycle it; in a damp basement it may run for long periods in summer.
