Buying Guide: Getting Allergy Relief on a Budget
Keep these points in mind before you buy.
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.
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.
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.
Genuine vs. compatible filters
Genuine filters keep the rated CADR and fit. Compatible filters cost less and many work well, but quality varies, so read recent reviews.
Save Money on Allergy Relief
Lower your yearly cost:
- Buy for the room you use most.
- Rinse the pre-filter often.
- Run low speed when air is clean.
- Stock filters in multi-packs.
