Coronavirus: Guelph scientist’s device approved to sanitize N95 masks

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.

Warriner thinks the units could be used to handle other medical items, from catheters to medical gowns.

The devices are already scheduled to be sent across Canada, including to Hamilton and Nova Scotia.

Orders have also been placed by the Niagara Health Region, Toronto EMS and the National Research Council in Ottawa.
