June 24, 2020
More than 99.9% of seasonal coronaviruses present in airborne droplets were killed when exposed to a particular wavelength of ultraviolet light that is safe to use around humans, a new study at Columbia University Irving Medical Center has found.
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 studys 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 today in Scientific Reports.

However there has been a breakthrough, its been proven that far-UVC light (207-222 nm) efficiently inactivates bacteria without harm to exposed mammalian skin.

I have seen ads for devices that a person wears that emits ozone, to fight the virus. One product has the device on the face mask.
