In the second layer, air moves through Alen's unique, electrostatically charged True HEPA that attracts and captures dust, pollen, pet dander, mold spores and other airborne pollutants. Alen then adds an antimicrobial compound to the True HEPA protecting the filter from harmful bacteria* and microbe growth.
