Buying Guide: How to Choose an Air Purifier for Allergies
Keep these points in mind before you buy.
True HEPA vs. HEPA-type
True HEPA captures at least 99.97% of 0.3-micron particles, the size that is hardest to catch. Pollen, dust mite debris and pet dander are larger, so a true HEPA filter traps them well. Avoid vague HEPA-type claims.
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.
Look for AHAM Verifide or ENERGY STAR
AHAM Verifide means an independent lab checked the CADR. ENERGY STAR models use less power, which matters when a purifier runs all day in allergy season.
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.
Noise and sleep mode
Allergies often peak at night. Look for a quiet sleep mode and a dimmable display, and size up so the purifier can run on a lower, quieter speed.
Count the filter cost
Check the price and life of the replacement filter before you buy. A cheap purifier with expensive filters can cost more over two years.
Skip ozone generators
Ozone can irritate the lungs. EPA warns against ozone generators sold as air cleaners. If a purifier has an ionizer, check that it is ozone-safe or switch it off.
Allergy-Season Purifier Tips
Get more relief from any purifier:
- Run it 24/7 in pollen season.
- Close windows on high-pollen days.
- Keep it in the bedroom at night.
- Change filters on schedule.
