We use uv light stands in the hospital. We will shut down a room and run a uv sanitizer for a bit. It works in some instances but it's not exactly something you can just leave running all the time. Everyone would probably have a sick tan tho.. To go with their skin cancer..

Those are 254nm. Far-UV is 222nm, which doesn't penetrate or damage skin or the eyes and seems to be completely safe to humans. The main issue is that it can generate ozone, but how significant that is is currently unknown.

Ozone is also used to disinfect, that's double the disinfection power!!!
