Polluted air first passes through Alen’s replaceable Pre-Filter to capture large particles, extending the life of the filter. In the second layer, air moves through Alen’s True HEPA material that attracts and captures dust, pollen, pet dander, mold spores and other airborne pollutants. We then add an antimicrobial compound to the HEPA type material, protecting the filter from harmful bacteria* and microbe growth. In the final layer, clean air passes through an extra thick layer of carbon for removal of odors and chemicals commonly found in the air from cleaning products, smoke, cooking, and various other household materials. The clean air is also passed through an antimicrobial treatment layer, removing and preventing growth of harmful mold and bacteria particles.

*Test results demonstrate a 99.99% kill rate on E. Coli and Staph Bacteria.
