4. BioGS® HEPA Filter

HEPA is the most trusted filtration technology in the world, used by hospitals, high-tech clean rooms, and scientific laboratories. Our advanced BioGS® HEPA filtration system is true-HEPA rated. It builds and improves on the traditional HEPA; composed of a proprietary fiber material, it traps allergens and particles 0.3 microns in size at 99.97% efficiency and particles less than 0.1 microns in size at higher than 99% efficiency3.

Our BioGS HEPA filters traps and reduces common allergens1 and bacteria2 trapped on the filter to support optimum filter efficiency and prolong filter life. Unlike traditional HEPA filters which could allow bacteria and virus to grow over time.

Traps allergen and particles 0.3 microns in size at 99.97% efficiency and over 99% efficiency for particles less than 0.1 microns3 Yes Yes
Reduces common allergens including dust mite matter, mold, pollen and pet dander 1 Yes No
Reduces the growth of bacteria and viruses on the filter 2 Yes No

6. Negative Ions

Negative Ions are odorless, tasteless and invisible molecules that are found near mountains, waterfalls and beaches. Some research studies show that negative ions help to alleviate depression and boost mental energy, but that's not all that these tiny molecules can do. Negative Ions help your air purifier by latching onto airborne particles, thus weighing them down. This allows the particles to get trapped more easily by your air purifier's filters, or to settle onto the floor where they can be picked up by your vacuum instead of accidentally inhaled.

CERTIFIED asthma & allergy friendly®

CERTIFIED asthma & allergy friendly

Why is the A3 air purifier CERTIFIED asthma & allergy friendly® by the Asthma and Allergy Foundation of America (AAFA)?
The asthma & allergy friendly® Certification Program, administered by the Asthma and Allergy Foundation of America (AAFA) in partnership with the international research organization Allergy Standards Limited (ASL), is an independent program created to scientifically test and identify consumer products that are more suitable for people with asthma and allergies. The Certification Program has included certifying air cleaners in order to address some of the contaminants that may be present in indoor air and to scientifically validate that air cleaners contribute to the goal of allergen reduction.

In order to be CERTIFIED, the A3 asthma & allergy friendly® air cleaners have passed testing and meet the following criteria:

  • The air cleaner can reduce bio-allergen level in a defined space.
  • The reduction in bio-allergen is a result of actual removal and not just re-distribution.
  • The air cleaner does not contribute to ozone levels in the home.
