Tobacco and Marijuana Smoke

Tobacco and Marijuana smoke air purifiers work in several steps. • A tar-trapping pre-filter removes sticky tar and other large particles • The HEPA traps 99.99% of fine airborne smoke particles • 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. The more activated carbon used in an air purifier, the more chemicals, gas and odor it can absorb.
