Engineering Minute – Yale Devises Method to Sterilize N95 Masks

Researchers at Yale New Haven Health System have devised a way to sterilize N95 respirator masks, which are currently in short supply due to the COVID-19 pandemic. Instead of getting thrown away, the masks that are considered to be in good shape are collected and placed in a room with special equipment that sterilizes them.

“The room gets filled with vaporized hydrogen peroxide, just like the hydrogen peroxide people use at home, and that is a very effective agent for sterilizing the masks, excuse me, the respirators from virus,” says Dr. Patrick Kenney of the Yale School of Medicine. The hospital hopes that they can sterilize up to 15,000 masks a day if necessary.
