The PuroAir Lite is powered by a robust 3layer filtration system designed for maximum indoor air quality. A prefilter reduces larger particles like dust3 and pet hair while extending the life of the filter. Next, the HEPA layer filters microscopic particles, and finally, the activated carbon filter reduces odors1, and smoke4. Working together, these layers filter up to 99.9% of airborne particles as small as 0.1 microns, including allergens4, dust3, pollen4, pet dander4, and smoke4, leaving your home filled with clean, healthy air
