What is Ultraviolet (UV) Light?
Ultraviolet (UV) light rays are the wavelengths outside of the visible light portion of the electromagnetic spectrum ranging from 100nm-4000nm. Broad-spectrum UV are naturally occurring, and are emitted from the sun, but UVC gets absorbed in the ozone layer of earth’s atmosphere.
Within the range of UV rays exists a range of rays called UVC (from 100-280 nanometers). These rays are medically categorized as germicidal, giving any rays in this range the ability to inactivate bacteria, viruses, fungi, and protozoa, including the coronavirus. Additionally, this technology is commonly used in water sterilization, medical facilities, and HVAC ducting at low power. It is environmentally friendly and chemical free.
How UV Works
When ultraviolet rays enter a cell, it disables the cell by damaging critical acids and proteins rendering the organism inactive or unable to reproduce.
Can UVC help Prevent COVID-19 Transmission?
Based on results of experiments, existing evidence shows that exposure to UVC can inactivate common microbes and serve as an effective method to no-touch disinfection. All bacteria and viruses tested to date respond to UV disinfection. Some organisms are more susceptible to UV disinfection that others, but all tested so far do respond at the appropriate doses.
How UVC Disinfection works.

UV Rays operate at a shorter wavelength than all visible light. The UV wavelength can penetrate viruses, bacteria and other infectious particles and cause physical destruction. The destruction of these particles renders them unable to infect and therefore disinfects the surface, liquid or air where they reside.
Is UV Disinfection safe?
Ultraviolet rays have been used for disinfection purposes for many years, so we know that with proper precautions in place, UV is safe to use for disinfection. As long as those operating the disinfection services are trained in the use of UV light and are themselves protected, the process is safe.
