The UV-C light neutralises the virus in the air at the top of the room while the normal hospital ventilation system circulates the air, exposing the virus to the UV-C. Staff can continue to work safely underneath.
New Zealand Country Leader for Signify (formerly Philips Lighting), Chris Morris, says laboratory research has shown that Philips UV-C disinfection upper air wall mount luminaires inactivated 99.99% of SARS-CoV-2, the virus responsible for the COVID-19 disease, in the air of a room within 10 minutes. At 20 minutes, the virus was below detectable levels.
“This indicates that, in most indoors situations, upper air UV-C can remove pathogens including SARS-Cov-2 from the air with greater efficacy than natural or mechanical ventilation,” says Mr Morris
