UV-C radiation is a known disinfectant for air, water and surfaces that can help mitigate the risk of acquiring an infection and has been used extensively for more than 40 years. All bacteria and viruses tested to date (many hundreds over the years, including various coronaviruses) respond to UV-C disinfection. There are no known pathogens resistant to UV-C. A clear indication that UV-C light can play a valuable part in any sanitization strategy.
Ultra-Violet (UV) light is divided into UV-A, UV-B and UV-C. UV-C is found within 100-280 nm range. Extensive research has shown that germicidal action is maximized at 265 nm with reductions on either side. UVC light is extremely effective in breaking down the DNA of micro-organisms. This means that they cannot replicate and cause disease.
