New Kind of Ultraviolet Light Safely Kills Airborne Pathogens Indoors, Scientists Say

Science Alert  March 28, 2022 One potential solution for controlling airborne pathogens is Krypton Chloride (KrCl) excimer lamps (often referred to as Far-UVC), which can efficiently inactivate pathogens, such as coronaviruses and influenza, in air. Research has demonstrated that Krypton Chloride (KrCl) lamps do not induce acute reactions in the skin or eyes, nor delayed effects such as skin cancer. An international team of researchers has shown that Far-UVC deployed in a room-sized chamber effectively inactivates aerosolized Staphylococcus aureus. At a room ventilation rate of 3 air-changes-per-hour (ACH), with 5 filtered-sources the steady-state pathogen load was reduced by 98.4% providing […]
