Alen BreatheSmart 45i True HEPA-Pure Filter: B4-Pure / FL40-Pure


Now True HEPA and Antimicrobial!

Designed for the Alen BreatheSmart 45i HEPA Air Purifier, the Alen Pure Filter combines two layers of filter technology to purify and freshen the air in your home.

  • Concerns covered: Allergies, Dust, Pollen, Dander, Mold and Bacteria
  • Treated with an antimicrobial coating to capture and kill germs and bacteria
  • True HEPA filtration removes 99.97% of airborne particles as small as 0.3 microns (about 56x smaller than a human hair)
  • Replaceable Pre-Filter layer extends the life of the filter
  • Eligible for Alen's convenient AutoShip Filter Plan with FREE Shipping
  • Model: BreatheSmart 45i

    Polluted air first passes through Alen's replaceable Pre-Filter to capture large particles, extending the life of the filter. In the second layer, air moves through a unique, electrostatically charged True HEPA material that attracts and captures dust, pollen, pet dander, mold spores and other airborne pollutants. We then add an antimicrobial Silver compound to the HEPA type material, protecting the filter from harmful bacteria* and microbe growth.  Relief from allergy and asthma symptoms has never been so simple.

    *Test results demonstrate a 99.99% kill rate on E. Coli and Staph Bacteria.


    There is no warranty for Alen filters.
