Regular filter replacement ensures your Alen HEPA air purifier's best performance>
The HEPA-OdorCell Filter 5-Pack is designed for the Alen® T500 HEPA Air Purifier.
With three advanced layers of filtration technology, the HEPA-Pure Filters remove dust, pet dander and pollen from the air you breathe. 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 style material that attracts and captures dust, pollen, pet dander, mold spores, and other airborne pollutants. Relief from allergy symptoms has never been so simple.
Alen recommends replacing your T500 HEPA-Pure 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.
