While UV disinfection is not a “new” technology, UV light is a proven disinfectant for surfaces, instruments, and air. With over 140 years of research behind it, Ultraviolet light has been repeatedly proven effective against pathogens, including C. diff, MRSA, E. coli, Salmonella, Norovirus, and many more. The ability of UV light to kill microorganisms is directly related to the energy dosage produced by the UV source as a function of spectrum, time and distance to the target.
Ultraviolet light attacks microorganisms at the DNA and RNA level. Microbes are not able to develop resistance to ultraviolet light, compared to their ability to form resistance to certain types of chemical disinfectants.
