WHAT IS UV-C LIGHT? (Reference - https://www.uvtechnology.co/aboutuvc.html)

Ultraviolet light in the C spectrum (UV-C) is energy-rich light with a wavelength of 200 - 400 nanometres (nm)

UV-C light is very versatile and can be used for disinfecting water, destroying harmful micro-organisms in other liquids, on surfaces, on food products and in 'air'.

With UV-C technology it is possible to destroy more than 99.99% of all pathogens within seconds, without addition of chemicals, without harmful side effects, inexpensively, highly efficiently and absolutely reliably.
