UVC, the kind that kills pathogens harms the skin and eyes and creates ozone. The article talks about using “Upper Room UV” which is just lights posted a safe distance away from humans above them which makes it considerably less effective at killing pathogens at the human level and also now theres a whole area of space where you cant go without risking harm from UVC like being on a ladder or some other platform.

UV also degrades lots of materials a lot faster

Edit: I meant Upper Room UV bot Far UV

Far UV refers to the wavelength, not distance from humans.
