Alen BreatheSmart FIT50 HEPA-Pure Replacement Filter 4 Pack: FF50-4


Designed for the Alen® BreatheSmart® FIT50 HEPA Air Purifier, the Alen HEPA-Pure Filter combines two layers of filter technology to purify and freshen the air in your home.

The HEPA-Pure Filter Captures Particles in 2 Steps 1. Polluted air first passes through Alen's washable Pre-Filter to capture large particles, extending the life of the filter. 2. In the second layer, air moves through a unique, electrostatically charged HEPA type material that attracts and captures dust, pollen, pet dander and mold spores

  • 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 6-12 months for severe concerns or when running your air purifier 24/7. Replace your filter every 12-18 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 of dust and particles. Allow it to completely dry before replacing.
  • Washing or vacuuming the white HEPA type material will damage the fibers and is not recommended.
