General Purpose

A general-purpose air purifier cleans indoor air in several steps: • A pre-filter removes larger particles • The HEPA traps 99.97% of fine airborne particles like dust and allergens • The deep-bed activated carbon filter adsorbs airborne chemicals, gases and odors While HEPA filters are fairly standard, activated carbon filters can vary in quality and effectiveness. Activated carbon works like a sponge to soak up airborne chemicals, gases and odors. The capacity of that “sponge” depends on its depth and size. The more activated carbon used, the more chemical, gas, and odor it can absorb.
