We compare verified CADR where available, room-size claims, filter type, filter replacement cost, noise complaints, energy use, app reliability, and warranty support. Air purifier rankings favor units with clear performance credentials and realistic ownership costs.
CADR measures how quickly a purifier cleans a room. For a 200 sq ft room, aim for a smoke CADR of 130+. Most manufacturers overstate room coverage - divide the CADR by 1.5 for a realistic coverage estimate.
True HEPA (H13 or higher) captures 99.97% of particles down to 0.3 microns, including most allergens, dust, and smoke. Avoid 'HEPA-type' or 'HEPA-style' filters - these are meaningfully less effective.
For allergy sufferers, look for 4-5 ACH in your room size. Multiply your room's square footage by ceiling height to get cubic footage, then match to the purifier's rated CFM output.
Some purifiers are cheap upfront but expensive to maintain. Calculate 2-year total cost of ownership (unit + filters) - a $100 purifier with $80/year filters often costs more than a $200 unit with $40/year filters.

They can be, but usually only the pre-filter is washable. The HEPA or main filter still needs replacement, so check both the washable claim and replacement filter cost.
No. A washable pre-filter catches larger hair and dust, while HEPA filtration handles much smaller airborne particles.
The Winix 5510 is the best first check because its washable pre-filter is useful for pet hair and dust while the HEPA and carbon stages handle finer particles and odors.
