Description of BioGS HEPA Filter
What is a HEPA filter
HEPA filters (High Efficiency Particulate Air) are defined by JIS standards as having a particle collection rate of 99.97% or more for particles with a particle size of 0.3 μm at a rated air flow, and an initial pressure loss of Air filter with performance of 245Pa or less”
HEPA filters are one of the only filtration technologies that can remove even the smallest particles, and are widely used in hospital operating rooms, ICUs, incubators, as well as medical laboratories and other high-tech research and manufacturing facilities around the world. Commonly used in controlled environments
What is “BioGS HEPA Filter”
"BioGS" means to Germicidal and Sterilize Bio (bacteria and viruses) in the air. Rabbit Air's "BioGS HEPA Filter" is an improvement over traditional HEPA filters and consists of a unique static-charged fiber material Not only does it collect 99.97% of 0.3μm particles, which is the standard for HEPA filters, but it also collects 99% of even smaller particles of 0.1μm. In addition, with general HEPA filters, captured bacteria and allergens may grow if they remain on the filter for a long period of time, but the "BioGS HEPA filter" captured allergens*1 and bacteria*2 that adhered. Afterwards, it reduces and inhibits their growth, so it is possible to extend the filter life while maintaining a high filter effect.

Allergens*1 and bacteria*2 adhered to the BioGS HEPA Filter decreased over time. I will continue
By reducing attached allergens*1 and suppressing the growth of bacteria and viruses*2, the filter will last longer while maintaining a high filter effect. I can

Mechanism of collection
In addition to the four standard collection mechanisms*3 of conventional HEPA filters, the “BioGS HEPA Filter” captures particles with the force of static electricity. This ensures maximum effectiveness even for the smallest particles
*3 Four standard collection mechanisms: (1) collection by inertial force, (2) collection by diffusion (Brownian motion), (3) collection by obstruction, (4) collection by gravity
Relatively large particles are captured by the filter fibers

When the inhalation speed is fast, relatively small particles are caught by hitting the filter fibers inevitably.
Relatively light particles are caught by hitting the filter fibers while riding in the air current.
Particles smaller than 0.3 μm collide with air molecules and their trajectories are disturbed. This makes it nearly impossible for it to pass through the filter without being trapped by the filter fibers.
BioGS HEPA filters are static Particles passing through the filter are captured by being attracted to the electrically charged filter fibers
Bacterial defense ability
Unlike conventional HEPA filters, BioGS HEPA filters inhibit the growth of bacteria and viruses attached to the filter Therefore, even after filtering the air in the space, there are very few bacteria, molds or viruses left on the filter.
