There are two ways to disinfect using UV:
Using deep UV with a short wavelength and using a combination of UV and a photocatalyst.

Why is 280nm the best choice?

Nichia launched its deep UV LEDs at 280nm because of the virucidal power described below as well as the lifetime and reliability of 280nm.
