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.
Comparison of allergens*1 and bacteria*2 on HEPA filters
Allergens*1 and bacteria*2 on HEPA filters accumulate over time. I will continue 
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
| Common HEPA filter | BioGS HEPA filter | |
|---|---|---|
| Captures 99.97% of 0.3μ particles and allergens | ○ Yes | ○ Yes |
| Captures more than 99% of 0.1μ particles and allergens | No | ○ Yes |
| Reduces major allergens such as dust, mites, mold, pollen, and pet dander attached to the filter | No | ○ Yes |
| Suppresses the growth of bacteria and viruses on the filter, making the filter last longer while maintaining its high effectiveness. | No | ○ Yes |

*2 Test sample: Influenza A virus (H1N1) - Tested by University of Tsukuba, University of Tottori, Japan Food Research Laboratories, National Research Institute of China Escherichia coli, Staphylococcus aureus - Tested by Japan Food Research Laboratories
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
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.
