Alen BreatheSmart FLEX HEPA-Pure Replacement Filter: B4-Pure / FL40-Pure


Now True HEPA and Antimicrobial!

Designed for the Alen® BreatheSmart® FLEX HEPA Air Purifier, the Alen HEPA-Pure Filter combines True HEPA filter technology with an antimicrobial treatment to purify and freshen the air in your home

  • Creates an allergy and asthma friendly environment by removing dust, pet dander, pollen, mold and bacteria from the air
  • True HEPA filtration removes 99.97% of particles as small as 0.3 microns
  • Treated with antimicrobial coating to capture and kill airborne germs and bacteria
  • Helps maintain a clean household by reducing dust
  • Replaceable Pre-Filter layer extends the life of the filter

    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 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 6-9 months for severe concerns or when running your air purifier 24/7. Replace your filter every 9-12 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 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.
