Researchers Identify N95 Respirator Decontamination Method Using Microwave-Generated Steam

N95 respirators are recommended by the CDC as the ideal protection method from COVID-19 and, although traditionally single-use, PPE shortages have necessitated the need for reuse. New research published this week in mBio, an open-access journal of the American Society for Microbiology, describes an effective, standardized method of decontamination for hospitals and healthcare centers facing N95 respirator shortages.

The researchers, from Beth Israel Deaconess Medical Center, Harvard University and Massachusetts General Hospital, have detailed a reproducible decontamination approach that all healthcare workers would be able to utilize.

"We identified an effective method of N95 decontamination by microwave-generated steam utilizing universally accessible materials. Our method resulted in almost complete sterilization after only 3 minutes of treatment and did not appear to affect the integrity of N95 filtration or fit with repeated treatment," the researchers write.
