Air Purifier Buying Guide for Bedrooms

CADR Rating

CADR (Clean Air Delivery Rate) measures how quickly a purifier cleans the air. For a bedroom, look for CADR of at least 150+ for dust. The higher the number, the faster it cleans.

Coverage Area

Rule of thumb: Choose a purifier rated for at least 1.5x your room's square footage to ensure proper air exchange rates.

Noise Level

For bedrooms, anything below 30 dB on its lowest setting is acceptable. Below 25 dB is excellent. Blueair and Levoit lead here.

Filter Type

True HEPA (H13) captures 99.97% of particles 0.3 microns and larger. Avoid "HEPA-type" — these are lower quality. Look for certified True HEPA.

Filter Replacement Cost

Factor in annual filter costs ($25-60/year). Winix and Coway have the most affordable replacement filters.

A: Yes — running on sleep/low mode all night is recommended. Most quality purifiers use very little electricity (7-50W) and have dedicated sleep modes.

A: Absolutely. True HEPA filters capture 99.97% of pollen, dust mites, pet dander, and mold spores — the main allergy triggers.
