What Makes an Air Purifier Good for Allergies
True HEPA Filtration
Look for "True HEPA" filters that remove 99.97% of particles 0.3 microns or larger. This captures most common allergens including:
- Pollen (typically 10-100 microns)
- Dust mite debris (0.5-50 microns)
- Pet dander (0.5-100 microns)
- Mold spores (1-20 microns)
Proper Room Coverage
Choose a purifier rated for at least your room size. For best results, select one rated for 1.5x your room's square footage.
CADR Ratings
Clean Air Delivery Rate (CADR) measures how quickly a purifier removes specific pollutants:
- Pollen CADR: Look for 240+ for large rooms
- Dust CADR: Higher is better for dust mite allergies
- Smoke CADR: Indicates performance on smaller particles

Consider ongoing costs when choosing an air purifier:
- Pre-filters: Washable, replace every 3-6 months
