Far ‐UVC Light at 222 nm is Showing Significant Potential to Safely and Efficiently Inactivate Airborne Pathogens in Occupied Indoor Locations

This article reviews both the safety of far-UVC, which has a clear mechanistic underpinning, and its efficacy, both in the laboratory and in full-sized rooms. Highlighted is the paper by Maet al. in this issue ofPhotochemistry and Photobiology which addresses the efficacy of far-UVC light (in this case at 222 nm) against a broad spectrum of common pathogens including SARS-CoV-2 and influenza viruses. From their data, and based on our understanding of the largely random nature of UVC-induced damage within the genome, far UVC would be expected to be effective against the next pandemic virus, if and when it emerges.
