Find the right dehumidifier capacity for your space in pints per day, based on square footage, ceiling height, and how damp the space actually is — the same AHAM sizing standard most dehumidifier manufacturers publish.

Moderately Damp: musty smell only in humid weather. Very Damp: always feels damp, persistent odor. Wet: damp spots on walls/floor. Extremely Wet: standing water or a flooding history.

Real dehumidifiers that clear this pint rating
Formula: base pint capacity comes from AHAM's published dehumidifier sizing table by square footage and dampness level (e.g. a 500 sq ft space needs roughly 10 pints/day at Moderately Damp up to 16 pints/day at Extremely Wet), scaled for
Ceiling Height ÷ 8, plus +5 pints for multiple daily occupants and +5 pints for in-space laundry drying. This mirrors the sizing guidance most dehumidifier manufacturers and Energy Star publish.
