Advanced HEPA Filtration Technology

Higher than 99% effective at trapping particles less than 0.1 microns3

What is HEPA?

HEPA stands for High Efficiency Particulate Air. One of the only filtration technologies capable of removing even the smallest particles, HEPA filters are commonly used in controlled environments around the world, including hospital operating rooms, ICUs and incubators, and even medical laboratories and other high-tech research and manufacturing facilities.

Why Is BioGS HEPA filtration better?

Our advanced BioGS HEPA filtration system builds and improves on the traditional HEPA—composed of an electrostatic-charged proprietary fiber material, it removes over 99.99% of airborne particles as small as 0.01 microns3. 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.

How does it filter?

In addition to the four standard trapping mechanisms of conventional HEPA filters, our BioGS filter adds another: electrostatic attraction. This advanced mechanism ensures the highest performance for even for the smallest particles.

Sieving: Large particles get trapped between filter fibers.
Inertial Impaction: Smaller airborne particles slam into filter fibers and get stuck as the air travels through the filter at high speed.
Interception: Lighter particles that follow the air stream can be captured on the fibers as it flows through.
Diffusion: Air and gas molecules help derail the trajectory of particles that are smaller than 0.3 microns. This makes it almost impossible for the particles to pass through the filter without getting captured by its fibers.
Electrostatic: Our BioGS HEPA filters are electrostatically charged—The particles flowing through the filter are attracted to the charged fibers.

Inertial Impaction

Smaller airborne particles slam into filter fibers and get stuck as the air travels through the filter at high speed.

Interception

Diffusion

Air and gas molecules help derail the trajectory of particles that are smaller than 0.3 microns. This makes it almost impossible for the particles to pass through the filter without getting captured by its fibers.

Electrostatic

Our BioGS HEPA filters are electrostatically charged—The particles flowing through the filter are attracted to the charged fibers.

Measured Performance

Rabbit Air's purifiers all use BioGS HEPA filters. Independent test shows our air purifier quickly reduces a plethora of pollutants from the air in a room.
