Dehumidifier Size Calculator
Estimate a planning range using room area, moisture condition, and temperature.
Treat this as a minimum comparison range using current pint ratings. Open layouts, active seepage, laundry, and high outdoor-air leakage can raise the load.
- Correct bulk water before increasing capacity.
- Confirm drainage, noise, and filter access.
- Check the exact model in the CPSC recall database.
Compare current models near this capacity only after checking drainage, temperature, and recall status.

The range adapts ENERGY STAR’s current guidance for portable dehumidifiers. It is a comparison starting point, not a load calculation or guarantee. Standardized capacity reflects defined test conditions; a cool basement may collect less water than the label suggests.
Classify the room
Musty is different from visible sweating or seepage. Choose the condition before looking at products.
Correct the source
Gutters, grading, leaks, and venting can matter more than another ten pints of rated capacity.
Check the system
Confirm temperature, drainage, electrical requirements, clearances, and recall status.
