UVC RESEARCH
Scientists agree that research on UVC disinfection conclusively demonstrates it eliminates up to 99% of viruses and bacteria.
Far-UVC light (222 nm) efficiently and safely inactivates airborne human coronaviruses.

“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.
Germicidal Efficacy and Mammalian Skin Safety of 222-nm UV Light.
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.

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.
