First of Its Kind COVID-19 Facemask Uses Ultraviolet Light to Kill Germs While Leaving Face Uncovered

Engineers at Pavvana (Denver, CO, USA) have developed a revolutionary protective mask that uses ultraviolet light to kill germs while leaving the face uncovered.

Pavvana's next-generation, patent-pending AirShield uses a curtain of air washed through UV-C sterilizing light to protect a user’s personal space at the same time it buffers others from the wearer, all while leaving the face open for work, play and family time. The Pavvana AirShield, worn on the forehead and consisting of UV-C light, air baffles, a rechargeable battery-powered fan and a head strap, is designed to kill 99.99% of airborne viruses and bacteria as the wearer breathes.

The AirShield is the first UV-C powered air shield produced for a mask, potentially replacing cloth and fabric-based face protections that haven't changed in decades. The Pavvana technology uses non-ozone producing UV-C bulbs that are encased so that no light escapes. The AirShield's rechargeable lithium ion battery can provide up to eight hours of comfortable protection, and there's nothing to clean or replace.

"We're excited and honored to bring this innovative, effective and comfortable product out into the world where it belongs," said Pavvana CEO Allbriton Robbins, a longtime designer for Fortune 500 firms. "It's a game-changer at a time when the daily routines of hundreds of millions of people have been torn up by a dangerous virus. We can help."
