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 a unique, electrostatically charged HEPA style material that attracts and captures dust, pollen, light smoke, mold spores and other airborne pollutants. 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, light smoke, cooking, and various other household materials.

Alen recommends replacing your T300/T100 HEPA-Fresh filter every 6 months for severe concerns or when running your air purifier 24/7. Replace your filter every 12 months for light concerns or when running the air purifier only as needed.
