Description. The ultraviolet light application is designed to irradiate the coil surface along with the drain pan. Germicidal protection is delivered at a wavelength of 254 nanometers in the light spectrum. Light at this wavelength is known as UV-C. Most bacteria, mold, and virus organisms are killed by exposure to UV-C light.

Ultraviolet-C (UV-C) refers to the short-wavelength (between 200 to 280 nanometers) radiant energy used in ultraviolet germicidal irradiation (UVGI) applications, which is highly effective at killing bacteria and viruses by destroying the molecular bonds that hold their DNA together. In doing so, the virus loses the ability to reproduce.
