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, 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.

Over time, the HEPA-Fresh Filter becomes overloaded with particles, decreasing its filtration performance. We recommend replacing your 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. Rinse or lightly vacuum the removable black Alen Pre-Filter as soon as it develops a layer of visible particles. Allow it to completely dry before replacing. Washing or vacuuming the white HEPA style material will damage the fibers and is not recommended.
