The University of Guelph says a device meant to decontaminate fresh produce is now being used to sanitize N95 masks for health-care workers during the coronavirus pandemic.
The technology, developed by U of G food scientist Keith Warriner, recently received approval from Health Canada. The process is waterless and combines ultraviolet light, hydrogen peroxide and ozone to make compounds that kill pathogens.
Each device can sanitize N95 masks in 30 seconds and can handle 800 masks an hour, according to the university. “It’s a game-changer,” Warriner said. “It combines the benefits of using hydrogen peroxide vapour and UV while overcoming the limitation of applying either alone.” [ Sign up for our Health IQ newsletter for the latest
