Designed for the Alen T500 HEPA Air Purifier, the Alen HEPA-Fresh Filter combines three layers of filter technology to purify and freshen the air in your home. 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 and pollen. 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 type material will damage the fibers and is not recommended.
