Effective Filtration

Next Generation HEPA Filtration

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.

Customized Filtration

One of the MinusA2's unique features is the ability to customize the filtration to target your specific concerns. Customized filter is one of the five filters in the MinusA2 air purifier. This bonus layer of protection enhances the cleaning power of your targeted pollutants. Each customized filter has a different proprietary coating or structure which helps target specific allergens or concerns.

Green Tea Filter

Composed of a unique blend of natural green tea ingredients, this filter physically traps airborne bacteria, mold spores, and virus-carrying particles.

Germ Defense Filter

Physically traps airborne bacteria, mold spores and particles that carry viruses.

Toxin Absorber Filter

Traps and reduces volatile organic compounds (VOCs) and other chemicals.

Pet Allergy Filter

Traps and reduces pet dander allergens.

Odor Remover Filter

Traps and reduces odors from pets, cigarettes and cigars, cooking and mildew.

We got you Covered!

The MinusA2 easily handles the most common allergens and pollutants in the home and many more.

Dust mites

Mold & fungi

Pet dander

Pollen

VOCs

Bacteria & particles that carry viruses

Six-stage purification & deodorization

Stage 1. Pre-Filter

The Pre-Filter effectively traps and reduces large sized allergens, dust, and particles.

Traps and reduces :

  • Dust mite matter allergen
  • Large particles
  • Pet hair
  • Pollen

Stage 2. Medium Filter

The Medium Filter traps and reduces airborne particles larger than 1 micron in size, such as pollen and pet dander allergens.

Traps and reduces :

  • Pet dander allergens
  • Dust particles
  • Pet hair
  • Pollen

Stage 3. BioGS® HEPA Filter

Our advanced BioGS HEPA filtration system builds and improves on the traditional HEPA—composed of an electrostatic-charged proprietary fiber material, it traps particles as small as 0.1 microns in size at 99% efficiency3. Unlike traditional HEPA filters that might allow the growth of bacteria and viruses over time, our BioGS HEPA filters trap and reduce common allergens1 and bacteria2 trapped on the filter to support optimum filter efficiency and prolong filter life.

  • Particles that can carry virus

Stage 4. Customized Filter

Tailor the MinusA2 air purifier to fit your personal needs. Choose from a variety of customized filters including Green Tea, Germ Defense, Pet Allergy, Odor Remover, or Toxin Absorber. Each filter is specially engineered to physically trap different types of chemicals, odors, allergens, and particles that carry viruses.

Green Tea

Composed of a unique blend of natural green tea ingredients, this filter physically traps airborne bacteria, mold spores, and virus-carrying particles.

Germ Defense

The Germ Defense filter is specially engineered to physically trap bacteria, mold and particles that carry viruses. This filter is perfect for children, elderly people, and those with compromised immune systems who are most sensitive to particles in the air.

Toxin Absorber

The Toxin Absorber filter is specifically designed to trap and reduce volatile organic compounds (VOCs) such as formaldehyde and toluene, which are commonly found in households and wildfires, as well as other airborne chemicals. It is ideal for use in new or renovated homes and offices.

Pet Allergy

The Pet Allergy filter is specially engineered to trap and reduce pet dander allergens. By reducing these contaminants, it allows you and your family to breathe in comfort at home.

Odor Remover

The Odor Remover filter is specially designed to trap and alleviate odors from pets, cigarettes and cigars, cooking, and mildew.

Stage 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.

Traps and reduces :

  • Cooking odors
  • Exhaust fumes
  • Greenhouse gases
  • Household odors
  • Pet odors
  • Tobacco smoke
  • Volatile organic compounds (VOCs)

Stage 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.

Rabbit Air moble app screen showing unit power status, air quality, fan speed, auto mode, pollen mode, mood light and light setting.

Rabbit Air products are in a class of air purification all their own. With highly sensitive odor and particle sensors, our advanced air purifiers detect the amount of pollutants in your environment and adjust their speed accordingly to assure the freshest air quality at all times.

(1) When it senses particles or odors in the air, the machine increases fan speed.

(2) The machine switches over to high speed until the air has been cleaned.

(3) Once the sensor detects a reduction in airborne pollutants, the machine will resume its original speed.

Our MinusA2's light sensor automatically cuts back on light pollution by defaulting to a low-energy, dimmed sleep lighting when the room darkens. When daylight returns or light levels increase, the MinusA2 resumes its normal mode.
