The HEPA-Pure Filter Captures Particles in 2 Steps 1. Polluted air first passes through Alen’s replaceable Pre-Filter to capture large particles, extending the life of the filter. 2. In the second layer, air moves through a True HEPA material that attracts and captures 99.97% of dust, pollen, pet dander and mold spore particles as small as 0.3 microns.
Caring for your HEPA-Pure Filter
- Over time, the HEPA-Pure Filter becomes overloaded with particles, decreasing its filtration performance. We recommend replacing your filter every 10-12 months when running your air purifier 24/7.
- Rinse or lightly vacuum the removable black Alen Pre-Filter as soon as it develops a layer of visible of dust and particles. Allow it to completely dry before replacing.
- Washing or vacuuming the white HEPA material will damage the fibers and is not recommended.
