Far-UVC light (222 nm) efficiently and safely inactivates airborne human coronaviruses – Nature, 2020

A direct approach to limit airborne viral transmissions is to inactivate them within a short time of their production. Germicidal ultraviolet light… is effective in this context but… can be a health hazard to skin and eyes. By contrast, far-UVC light efficiently kills pathogens potentially without harm to exposed human tissues.

Air Disinfection for Airborne Infection Control with a Focus on COVID‐19: Why Germicidal UV is Essential – Photochemistry and Photobiology, 2021

Only two established room‐based technologies are available to supplement mechanical ventilation: portable room air cleaners and upper room germicidal UV air disinfection… SARS‐CoV‐2 is highly susceptible to GUV, an 80‐year‐old technology that has been shown to safely, quietly, effectively and economically produce the equivalent of 10 to 20 or more air changes per hour under real life conditions.
