Yes, among other things. It also has negative side effects on the surface it's cleaning. But there's some interesting IP in the space to maximize the effectiveness while minimizing time and energy used. Not all UV-C is the same.

Far UVC is supposedly safe for humans.

> To continuously and safely disinfect occupied indoor areas, researchers at Columbia University Irving Medical Center have been investigating far-UVC light (222 nm wavelength). Far-UVC light cannot penetrate the tear layer of the eye or the outer dead-cell layer of skin and so it cannot reach or damage living cells in the body.
