  • Correct bulk water before increasing capacity.
  • Confirm drainage, noise, and filter access.
  • Check the exact model in the CPSC recall database.
Optional shopping step

How to use the result

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.

01

Classify the room

Musty is different from visible sweating or seepage. Choose the condition before looking at products.

02

Correct the source

Gutters, grading, leaks, and venting can matter more than another ten pints of rated capacity.

03

Check the system

Confirm temperature, drainage, electrical requirements, clearances, and recall status.
