How We Chose the Best Budget Air Purifier for Basement

To choose the best budget air purifier for basement, we compared popular HEPA and carbon air purifiers on Amazon by CADR, carbon content, coverage and owner feedback for damp, musty basements.

EPA says to keep indoor humidity below 60 percent, ideally 30 to 50 percent, and to dry wet areas within 24 to 48 hours; see the EPA brief guide to mold, moisture and your home.

Buying Guide: Cheap but Effective

Keep these points in mind before you buy.

Match CADR to room size

CADR (Clean Air Delivery Rate) shows how fast a purifier cleans. AHAM suggests a smoke CADR of at least two-thirds of the room area, so a 150 sq ft room needs about 100 CFM.

Basement placement

Set the purifier where you spend time, such as a den or laundry area, off the damp floor and away from walls and curtains so airflow is not blocked.

A washable pre-filter helps

A pre-filter catches hair, lint and large dust before the HEPA filter. Vacuum or rinse it every few weeks, as the manual directs, so the main filter lasts longer.

Budget Tips

Get more from a cheap purifier:

  • Close the door to the room you use.
  • Run it on Auto or medium.
  • Keep it 1–2 feet from walls.
  • Vacuum the pre-filter.
