• Description:
  Supplies of N95® filtering facepiece respirators (FFRs) can become depleted during widespread outbreaks of infectious respiratory illnesses. To supplement the national inventory of NIOSH Approved® N95 FFRs during times of extreme shortages, FFR reuse following decontamination is a possible strategy. Decontamination is a process to reduce the number of pathogens on used FFRs before reuse. An effective FFR decontamination technique should significantly reduce the pathogen burden, but not reduce a respirator's filtration performance or its ability to fit properly. Another consideration is that no hazardous chemical residue should be left on the FFR following the decontamination process. During non-emergencies, FFRs are considered limited-use products and are not approved for decontamination and reuse; however, when there are known FFR shortages, FFR decontamination and reuse may need to be implemented as a crisis capacity strategy to ensure continued availability after conventional and contingency strategies have been implemented. On March 29, 2020, the U.S. Food and Drug Administration (FDA) issued the first Emergency Use Authorization (EUA) for a decontamination technique to be considered to offset N95 FFR supply shortages with subsequent EUAs and revisions issued. The purpose of this assessment was to determine the effects of various decontamination processes on the particulate filtration performance, manikin fit, and strap integrity of various N95 FFR models. The assessment did not assess the reduction of the pathogen burden by the decontamination procedure. [Description provided by NIOSH]
