Best Air Purifier for Small Rooms
Not all air purifiers are equal — true HEPA filters capture 99.97% of particles down to 0.3 microns, covering most allergens, dust, pet dander, and wildfire smoke. For rooms under 300 sq ft, a compact unit runs quieter and more efficiently than an oversized whole-home system.
