Recent studies have shown that an asymptomatic SARS-COV-2 carrier can have up to 100,000,000 copies of the virus per mL in their mouth and expel over 16 infectious doses of virus per minute while talking and active.
Fortunately, SARS-COV-2 is highly susceptible to germicidal UV irradiation; in fact, it is three times more susceptible to UV than common influenza virus. Our Gpurify ultraviolet irradiation delivers an ultraviolet dosage of in excess of 50 mJ/cm2. The photolytic technology contained in the unit was demonstrated to inactivate SARS-CoV-2 virus in direct testing.
Battelle Research Labs performed SARS-CoV-2 bioaerosol elimination testing of the Gpurify photolytic filtration technology - The purpose of the study was to determine effectiveness of the Aerobiotix C-band ultraviolet (UVC) air filtration unit to remove SARS-CoV-2 bioaerosols under challenge conditions with viable virus. Within the limitations of this study, the Aerobiotix unit was successful in removing viable SARS- CoV-2 bioaerosols compared to controls. While the unit is much bigger, the technology and effectiveness are the same.
In regular UV air sanitizers, air goes past the UV lamps at high speed, not allowing enough time under the UV rays to get an adequate UV killing dose. The patented photolytic chamber contains several hundred tubular units, which are made from a unique material which allows UV rays to pass, but not germs.
Simple UV lamps will not kill all the germs unless exposure time is boosted. The extended germs capture time increases UV kill power up to 100X over UV alone.
This design, which is used in critical hospital disinfection systems, is the ONLY technology directly tested against airborne SARS CoV-2 virus, as well as bacteria, spores, and other viruses.
The Technical Explanation:
The biocidal technology is a solid-state germicidal irradiation system which utilizes C band ultraviolet light (UVC) at a 254 nm wavelength diffused into a solid media which is gas and radiation permeable. The media design allows for maximal airflow and surface area. While organisms are slowed or trapped in the solid media, they are inactivated by the internal UVC dosage. This has the effect of increasing the inactivation efficiency over prior UV technologies.
The ultraviolet lamps are completely sealed within the unit, so there is no risk of exposure of room occupants to UV radiation, which can be hazardous. The unit has been independently tested for UV emissions under international standards. The device also does not emit ozone.
The device contains a unique photolytic chamber, with randomly oriented transmission elements which is a patented Aerobiotix technology, to improve the efficacy of ultraviolet decontamination. This system is used in critical hospital applications on a global basis.
Unlike prior devices which depend on passive air currents to expose airborne pathogens, Gpurify contains internal fans in the ultraviolet chamber.
