Abstract
Abstract A wall-mounted, far-ultraviolet-C light technology reduced aerosolized bacteriophage MS2 by >3 log 10 plaque-forming units within 30 minutes. Vegetative bacterial pathogens on steel disk carriers in the center of the room were reduced by >3 log 10 after 45 minutes of exposure, but Candida auris and Clostridioides difficile spores were not.
