Oracle Lighting has developed a new ultraviolet light system to be worn under face masks that will sanitize the air, neutralize live viruses such as COVID-19 and protect against the 5% of particulate that manages to get past N95 masks.
Existing air filtration masks trap particles from incoming air in the cloth material worn on the face, but they do not disinfect or sanitize the particles on the masks, which can become saturated with live viruses, pathogens or other microorganisms and cause infection through cross-contamination.
