Impact of a novel mobile high-efficiency particulate air–ultraviolet air recirculation system on the bacterial air burden during routine care

Aerosol transmission of pathogens can result in the rapid spread of disease. Introduction of a mobile air recirculation system based on high-efficiency particulate air filtration, photochemical oxidation, and germicidal ultraviolet light significantly decreased the bacterial load by over 40% under routine care in an emergency department. Application of this new technology promises to reduce the aerosol pathogen burden, thereby decreasing exposure risk and providing a safer environment for patient care.
