Reducing Airborne Pathogens with Germicidal Technology

This white paper discusses the application of Ultraviolet Germicidal Irradiation (UVGI or UV-C) technology to reduce airborne pathogens in various settings. It outlines the historical context of UV-C use, noting its resurgence due to antibiotic-resistant microorganisms. The document details three primary deployment methods: upper-air/room systems, HVAC airstream disinfection, and surface irradiation. The focus is on upper-air/room systems, which are designed to kill airborne infectious agents as they rise into the upper areas of spaces like classrooms and hospitals. The paper also references historical studies demonstrating the effectiveness of UV-C in reducing infection rates, such as those conducted by William F. Wells and Dr. Deryl Hart. Additionally, it explains the mechanisms by which UV-C disrupts microbial DNA, rendering pathogens incapable of reproduction. The conclusion emphasizes the importance of UV-C technology in infection control, particularly in high-occupancy environments, and encourages facility managers to consider its implementation as a safeguard against airborne diseases.
