Killing Airborne Bacteria and Viruses in Pig Barns With Plasma Device

Researchers at the University of Michigan are testing a prototype device designed to filter the air of a pig barn at a pork production farm by using nonthermal plasma to inactivate airborne pathogens to prevent the spread of disease.

The research team has previously demonstrated that a lab-scale device can achieve greater than 99% inactivation of an airborne viral surrogate, MS2 phage, a virus that infects E.coli bacteria. This new field prototype will test the system’s capabilities in a real farm environment.
