Buying Guide
Choosing the right air purifier for allergies depends on room size, filter type, and noise level. First, measure the square footage of the room you want to purify. Most units are rated for specific room sizes; for best results, choose a model that can cycle the air 4-5 times per hour. Look for a True HEPA filter, which captures 99.97% of particles as small as 0.3 microns, including allergens like pollen and dust mites. Activated carbon filters help remove odors and VOCs. Consider CADR (Clean Air Delivery Rate) for smoke, dust, and pollen; higher values mean faster cleaning. Also check noise levels (decibels) if you plan to use it in a bedroom. Finally, think about filter replacement costs and frequency. For large rooms, the Winix 5500-2 is a powerhouse with a washable pre-filter. For medium rooms, the Honeywell HPA300 offers high CADR and reliable performance. And for a compact but mighty option, the Coway Airmega 200M fits small spaces beautifully.
