UV-C lamps use ultraviolet radiation to purify the air of bacteria, mould, fungal spores and viruses.
This technology has been used for many years to sanitise objects, surfaces and to purify water. Recent Japanese and Italian studies have demonstrated its effectiveness on COVID-19 by defining the dose of UV-C rays required for their inactivation.
The bactericidal and virucidal action is carried out with low-pressure mercury lamps through direct radiation of the air flow with a wavelength of 254 nm.
