scientific facts about far-uvc
Far-UVC is a short wavelength of 222nm which provides the first human and animal safe, practical, and effective countermeasure for infectious disease and pathogens in occupied spaces.
Depending on the length of exposure, UVC 222 nm naturally kills up to 99.9% of bacteria and viruses including coronaviruses in ~16 minutes. More
Unlike conventional 254-nm UVC, 222-nm UVC efficiently kills pathogens and is harmless to mammalian cells. More
what is FAR-uvc?
Our disinfecting technology uses Far-UVC. Dr David Brenner gives a TED Talk about a new weapon to fight against superbugs. Several years ago, Dr. Brenner and his colleagues hypothesized long before COVID that a narrow spectrum of ultraviolet light called far-UVC could kill microbes without damaging healthy mammalian tissue. "Far-UVC light has a very limited range and cannot penetrate through the outer dead-cell layer of human skin or the tear layer in the eye, so it's not a human health hazard. But because viruses and bacteria are much smaller than human cells, far-UVC light can reach their DNA and kill them," he said.
It is in this narrow spectrum HyGear's technology operates.
Scientists agree that research on UVC disinfection conclusively demonstrates it eliminates up to 99% of viruses and bacteria.

“Based on our results, continuous airborne disinfection with far-UVC light at the current regulatory limit could greatly reduce the level of airborne virus in indoor environments occupied by people,” says the study’s lead author David Brenner, PhD, Higgins Professor of Radiation Biophysics at Columbia University Vagelos College of Physicians and Surgeons and director of the Center for Radiological Research at Columbia University Irving Medical Center. The research was published in Scientific Reports.

Collectively, our studies suggest that far-UVC light (200–225 nm), unlike conventional UV germicidal lamps, has considerable promise to be a safe and inexpensive modality for SSI reduction, while being cytotoxic to both drug-resistant and drug-sensitive microbes.

Upper-room ultraviolet air disinfection might help to reduce COVID-19 transmission in buildings: a feasibility study.
Clive B. Beggs, Eldad J. Avital | October 2020
We were able to demonstrate that the SARS-CoV-2 virus is relatively easily inactivated by UV-C light and that when aerosolized the virus is likely to have a UV susceptibility constant, Zur, that is similar to that exhibited by other coronaviruses in air. This suggests that SARS-CoV-2 when suspended in air should be reasonably easy to inactivate using UV light at 254 nm. As such, upper-room UVGI may have potential as an intervention to inhibit the transmission of COVID-19 in buildings, especially in situations where achieving high ventilation rates might otherwise be impractical. The research was published in PeerJ.

Implementation of this “no-touch” technology in various hospitals has documented a sustained reduction in surface microbial contamination, reduced cross contamination, and a reduced spread of multi-drug resistant bacterial infections. The Research was published in the International Journal of Environmental Research and Public Health.
