20-Pack of Alen HEPA-Silver FiltersDesigned for the T100/T300, this filter combines three layers of filter technology to purify and freshen the air in your home while protecting the filter against bacteria and microbes. Contains 20 filters. Polluted air first passes through Alen's washable Pre-Filter to capture large particles, extending the life of the filter. In the second layer, air moves through a unique, electrostatically charged HEPA type material that attracts and captures dust, pollen, pet dander, mold spores and other airborne pollutants. Alen's anti-microbial Silver-Ion threads are woven into the HEPA type material, protecting the filter from harmful bacteria* and microbe growth. In the final layer, clean air passes through a layer of Alen's Activated Carbon, reducing light odors and chemicals commonly found in the air from cleaning products, smoke, cooking, pets and various other household materials.
*Test results demonstrate a 99.99% kill rate on E. Coli and Staph Bacteria.Note: The Alen T300 HEPA Air Purifier requires two (2) filters. The Alen T100 HEPA Air Purifier requires only one.
