Best air purifiers for allergies in a bedroom?
I’m looking for an air purifier mainly for allergies in a bedroom. Seasonal pollen, dust, and pet dander seem to make my congestion worse at night, and I’d like something that can run quietly while I sleep.
Room size: About 150–250 sq ft.
Budget: Around $100–$250, plus reasonable filter costs.
What I want:
- True HEPA filtration and a CADR appropriate for the room
- Quiet enough for overnight use
- Reliable availability of replacement filters
- No ionizer or ozone-generating features
- Simple controls; smart/app features are optional
Options I keep seeing:
- Coway Airmega AP-1512HH Mighty
- Levoit Core 300S / Core 400S / Vital 200S
- Blueair Blue Pure 311i Max
- Winix 5500-2
- Honeywell HPA100 / HPA200
- GermGuardian models
I know an air purifier will not solve every allergy trigger, especially things that settle on surfaces, but I’m hoping it can help reduce airborne pollen, dust, and dander in the room. For allergies, it seems most important to match the purifier’s CADR to the room and use a true HEPA filter; HEPA filters are designed to capture at least 99.97% of particles at 0.3 microns.
What air purifier has actually made a noticeable difference for your allergies, especially for sleeping?
