MinusA2 Six-Stage Purification and Deodorization
1. Pre-Filter
The Pre-Filter physically traps large airborne particles, dust, and common household allergens.
Captures:
- Dust mite matter
- Large particles
- Pet hair
- Pollen
2. Medium Filter
The Medium Filter physically traps airborne particles larger than 1 micron in size, including common household allergens like pollen and pet dander.
Captures:
- Pet dander1
- Dust particles
- Pet hair
- Pollen
3. 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 HEPA-rated. It builds and improves on the traditional HEPA; composed of a proprietary fiber material, it traps airborne particles 0.3 microns in size at 99.97% efficiency and achieves over 99.99% removal of ultrafine 0.01-micron particles3.
The BioGS HEPA filter physically traps common household allergens (such as pet dander and dust mite matter)1 and airborne bacteria2, and inhibits the growth of odor-causing mold and mildew on the filter media4.
| Features | Rabbit Air HEPA Filter | Typical HEPA Filter |
|---|---|---|

| Tested to achieve >99.99% removal of 0.01 micron particles3 | Yes | No |
| Traps common household allergens (such as pet dander and dust mite matter)1 and airborne bacteria2, and particles that carry viruses2 | Yes | Yes |
| BioGS Filter Technology | ||
| Inhibits the growth of odor-causing mold and mildew on the filter media4 | Yes | No |
| Prolongs optimal filter efficiency | Yes | No |
4. Customized Filter
Tailor the MinusA2 air purifier to fit your personal needs. Choose from a variety of customized filters including Germ Defense‡, Pet Allergy, Odor Remover, or Toxin Absorber. Each filter is specially engineered to physically trap different types of chemicals, odors, common household allergens, and particles that carry viruses.
Traps and adsorbs volatile organic compounds (VOCs) and other airborne chemicals.
Captures pet dander1 and physically traps other common household allergens.
Traps and adsorbs odors from pets, cigarettes and cigars, cooking, and mildew.
5. Activated Carbon Charcoal Filter
Made of high-grade granular activated carbon, our AC filter is much more effective than typical AC filters, which are coated with a thin layer of activated carbon. Chemicals and common household odors can be effectively reduced.
Captures:
- Cooking odors
- Exhaust fumes
- Household odors
- Pet odors
- Tobacco smoke
- Volatile organic compounds (VOCs)
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®

Why is the MinusA2 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 MinusA2 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.
