UVC light is the type of UV light that’s most effective at killing germs. It can be used to disinfect surfaces, air, and liquids.

UVC light kills germs like viruses and bacteria through damaging molecules like nucleic acids and proteins. This makes the germ incapable of performing the processes that it needs to survive.

UVC light can effectively kill SARS-CoV-2 or other coronaviruses in liquids, on surfaces, or in the air. Due to the fact that it presents less of a health hazard, far-UVC may be a good option for disinfection.
