How does UV light disinfection work?
Ultraviolet radiation has enough energy to break down the chemical bonds between electrons and atoms. That’s why it can be harmful to eyes and skin (sunburn), but why it is also benefit for disinfecting surfaces and purifying air.
UV-C disinfection uses light to break down the chemical compounds in a micro-organism like bacteria, spores and viruses so they cannot multiply. Over the years, many hundreds of bacteria have been tested, and all of them respond to UV-C disinfection – including various coronaviruses. In laboratory tests, Signify’s UV-C light sources reduced SARS-CoV-2 virus infectivity on a surface to below detectable levels in as few as 9 seconds. A clear reason why UV-C light should play a key role in your COVID-19 protection strategy.
