Cold Plasma can Kill 99.9% of Airborne Viruses

Civil and Environmental Engineering Professor Herek Clack (left) and members of his team set up a lab-scale non-thermal plasma device that has previously been proven to achieve greater than 99% inactivation of an airborne viral surrogate, MS2 phage, a virus that infects E.coli bacteria at the Barton Farms family pig farm in Homer, MI.

Dangerous airborne viruses are rendered harmless on-the-fly when exposed to energetic, charged fragments of air molecules, University of Michigan researchers have shown. They hope to one day harness this capability to replace a century-old device: the surgical mask.

The U-M engineers have measured the virus-killing speed and effectiveness of nonthermal plasmas – the ionized, or charged, particles that...
