Alen BreatheSmart 45i True HEPA Fresh Filter: B4-Fresh / FL40-Silver-Carbon


Now True HEPA and Antimicrobial!
Designed for the BreatheSmart 45i HEPA Air Purifier, the Alen Fresh Filter combines three layers of filter technology with an antimicrobial treatment to purify and freshen the air in your home while protecting the filter against bacteria and microbes.

  • Concerns covered: Allergies, VOC's, Smoke, Dust, Mold and Bacteria
  • Finished with an antimicrobial Silver treatment to capture and kill mold and bacteria
  • True HEPA filtration removes 99.97% of airborne particles as small as 0.3 microns (about 56x smaller than a human hair)
  • Equipped with carbon to absorb odors and household chemicals
  • Pre-Filter layer extends the life of the filter
  • 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. In the final layer, clean air passes through a layer of Alen's Activated Carbon, reducing light odors and chemicals commonly found in the air from cleaning products, smoke, cooking, pets and various other household materials. These factors all combine to make the 45i Fresh filter the best choice for a room with a combination of multiple air quality issues.

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


    There is no warranty for Alen filters.
