New Tech Face Masks Use UVC Light

Companies are integrating UVC into face masks in two ways: cleaning internal filters to keep them effective longer (though it degrades N95s), and cleaning the air you’re about to breathe with UVC light, effectively adding another layer of protection. The latter can be found in the UVMask from Canada-based UM Systems. The company has raised more than $7 million on crowdfunding platforms Indiegogo and Kickstarter. It is the first active UV-C mask that instantly filters pathogens, smoke, pollution, pollen and leaf mulch.
