How the ranking works. We rank 218 room air purifiers by certified pollen CADR — the AHAM test closest to airborne allergens — breaking ties toward larger room size then higher average CADR. CADR, PM2.5, room size and ENERGY STAR come from the AHAM Verifide directory; average CADR is computed by us. No star ratings, no paid placement. Missing values show "—". See our methodology.
Frequently asked questions
Which CADR number matters most for allergies?
Pollen CADR. AHAM tests three particle sizes — dust, smoke and pollen — and the pollen test uses the largest particles, which is closest to real allergens like pollen and mold spores. A high pollen CADR means the unit pulls those allergens out of your air fastest. We rank this list by pollen CADR.
Do I need a true HEPA filter for allergies?
Yes, choose true HEPA (H13). It captures 99.97% of particles down to 0.3 microns, which covers pollen, mold and pet dander. "HEPA-Type" filters miss more of the small stuff. We flag the filter type on every row.
How big a purifier do I need for my bedroom?
Match the CADR to the room. AHAM’s suggested room size assumes about 4.8 air changes an hour. For allergy relief you want faster cleaning, so pick a unit rated for a room larger than yours — a rough rule is a pollen CADR at least two-thirds of your room’s square footage.
Should I run it all day during allergy season?
Yes. Allergens settle and re-circulate, so continuous running on a medium setting keeps the count low. Check the replacement-filter cost before you buy — that recurring cost matters more than the sticker price.
Are these picks paid placements?
No. We take no payment for placement and publish no star ratings. Each pick is the top unit on one stated AHAM number. Re-sort the full table by any column to rank the field yourself.
