Dehumidifier Size Calculator
Determine the right dehumidifier capacity (pints per day) based on your room size and moisture level.
Recommended Size
Dehumidifier capacity is measured in pints of moisture removed per day and depends on room size and dampness level.
Sizing guide (AHAM standards):
| Room Size | Moderately Damp | Very Damp | Wet | Extremely Wet |
|---|---|---|---|---|
| 500 sq ft | 10 pt | 12 pt | 14 pt | 16 pt |
| 1,000 sq ft | 14 pt | 17 pt | 20 pt | 22 pt |
| 1,500 sq ft | 18 pt | 22 pt | 26 pt | 28 pt |
| 2,000 sq ft | 22 pt | 27 pt | 32 pt | 35 pt |
| 2,500 sq ft | 26 pt | 32 pt | 38 pt | 42 pt |
Dampness levels:
- Moderately damp: Musty smell in humid weather
- Very damp: Damp spots on walls/floor, musty smell always
- Wet: Sweating walls, seepage present
- Extremely wet: Standing water, flooding history
Energy Star dehumidifiers use 15-20% less energy than standard models.
