The FDA has issued emergency-use authorizations (EUA) for sterilizing and reprocessing N95 masks, according to an article on the HCPro website.
Approximately 4 million N95 or N95-equivalent respirators can be decontaminated per day in the U.S. for reuse by healthcare workers in hospital settings, according to the agency.
N95 masks are placed in a room, sprayed with vaporized hydrogen peroxide using a special machine and left to dry.
A mask can be reprocessed up to 10 times for single-user reuse.
