August 21, 2020  The FDA issued an emergency use authorization (EUA) to NovaSterilis, Inc. for its Nova2200, which uses the NovaClean decontamination process. Nova2200 can be used to decontaminate compatible N95 respirators for single-user reuse by healthcare personnel (HCP) to prevent exposure to pathogenic biological airborne particulates when there are insufficient supplies of face-filtering respirators (FFRs) during the COVID-19 pandemic.
