Buying Guide: Choosing a Home Air Purifier for Allergies
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.
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.
Auto mode and sensors
A particle sensor lets Auto Mode raise the fan when pollen or dust spikes and drop it when the air is clean, which saves power and noise.
Place it near where you breathe
Put the purifier in the bedroom or main living area, a few feet from walls and furniture, and keep doors and windows closed on high-pollen days.
Control the source first
EPA advises source control and ventilation first. Encase mattresses and pillows, wash bedding hot weekly, vacuum with HEPA and keep humidity in check.
Whole-Home Allergy Tips
Pair your purifier with these habits:
- Change the HVAC filter.
- Shoes off at the door.
- Vacuum with HEPA weekly.
- Shower after outdoor time.
