HEPA Air Purifier in Bedroom

Moderate evidence$80-200 plus filter replacements

How to use

Run a HEPA-certified air purifier in your bedroom continuously during allergy season. Change filters on schedule. Keep windows closed on high-pollen days.

How it works

True HEPA filters capture 99.97% of airborne particles 0.3 microns or larger, including pollen and mold spores. Reducing allergen load in the sleeping environment supports overnight recovery.

Where to buy

Home goods stores and Amazon. Coway, Levoit, and Winix are well-rated brands ($80-200).

Typical cost: $80-200 plus filter replacements

Safety notes

Match the purifier to the room size (check CADR rating vs square footage). Ionizers and ozone generators are not the same as HEPA and can irritate airways.
