Meet the Air Curtain: An Invisible Mask to Kill Viruses, Block Nearly All Aerosols

An air curtain shooting down from the brim of a hard hat can prevent 99.8 percent of aerosols from reaching a worker’s face. Watch this video to learn more about the technology, which was created by University of Michigan startup Taza Aya.

“Our air curtain technology is precisely designed to protect wearers from airborne infectious pathogens, using treated air as a barrier in which any pathogens present have been inactivated so that they are no longer able to infect you if you breathe them in,” said Herek Clack , U-M associate professor of civil and environmental engineering. “It’s virtually unheard of—our level of protection against airborne germs, especially when combined with the improved ergonomics it also provides.”
