MinusA2 Air Purifier
MINUSA2 ULTRA QUIET AIR PURIFIER
EFFECTIVE 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

Defense
Absorber
Allergy
Remover
The Germ Defense filter is specially engineered to trap and reduce 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.
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.
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.
INTELLIGENT PURIFICATION
Get acquainted with our MinusA2 SPA-780N. Outfitted with wireless internet capabilities, this unit allows you to monitor air quality and control purification in your home whether you’re sitting on the couch or away from the house. Enjoy the effortless experience of clean air with this cutting edge version of our favorite machine.
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.ttings
