UVC light inactivates the SARS-CoV-2 (COVID-19) virus and other airborne pathogens, improving indoor safety.
With schools taking precautions against COVID-19, an effective tool in their arsenal is a new type of “germicidal” LED fixture. This specialized, enclosed LED fixture draws in air and irradiates it with ultraviolet light (UV), significantly improving indoor safety by providing continuous airborne disinfection of the SARS-CoV-2 (COVID-19) virus as well as other airborne viruses, bacteria, and germs.
While traditional UV fixtures have been used for many years to clean surfaces, they could not be safely used in occupied spaces. The new type is designed to safely and constantly disinfect indoor air in occupied rooms.
Although LED light fixtures normally emit visible light with a 400 nm -700 nm wavelength, lower frequency ultraviolet (UV) light LEDs can effectively kill such pathogens. UVC, a very powerful ultraviolet light wavelength between 100 nm-280 nm, is viricidal, bactericidal, and fungicidal since it passes through the outer wall of the pathogen and causes damage at the molecular level.
