Duke Starts Novel Decontamination of N95 Masks to Help Relieve Shortages

Facing a critical shortage of N95 face masks that block the coronavirus, Duke Health research and clinical teams have confirmed a way to use existing vaporized hydrogen peroxide methods to decontaminate the masks so they can be reused.

The process uses specialized equipment to aerosolize hydrogen peroxide, which permeates  the layers of the mask to kills germs, including viruses, without degrading the mask material. “This is a decontamination technology and method we’ve used for years in our biocontainment laboratory,” said Scott Alderman, associate director of the Duke Regional Biocontainment Laboratory.
