Disinfecting N95 masks for reuse during COVID-19 pandemic

What is the best way to disinfect an N95 mask? With a shortage of masks during the COVID-19 pandemic, doctors need to know if masks can be cleaned and still remain effective at blocking coronavirus particles https://news.engin.umich.edu/2020/04/engineers-work-to-decontaminate-n95-masks-for-front-line-medical-personnel/

University of Michigan engineers and clinicians are working quickly to address the shortage of these masks by developing efficient, effective and scalable ways of disinfecting masks, which are typically discarded after one use.

Krista Wigginton, associate professor of civil and environmental engineering, and Nancy Love, the Borchardt and Glysson Collegiate Professor of Civil and Environmental Engineering, are working together to specifically test the best way to treat N95 masks, exploring the use of ultraviolet light, wet heat and hydrogen peroxide. The team also includes Lutgarde Raskin, Lucinda Li, Nicole Rockey, Peter Arts and Katherine Harrison.

Another team at U-M is figuring out how many times these masks can be treated while still effectively stopping coronavirus-scale particles: https://www.youtube.com/watch?v=P9uYVVkIn9I

The overall effort is a result of a partnership between the College of Engineering and Michigan Medicine to identify problems and assign U-M engineers to address them. Deactivating viruses on N95 masks is among the first, most-pressing issues doctors on this U-M COVID-19 Rapid Reaction Steering Committee identified.
