This report summarizes the NIOSH assessments of filtration efficiency, manikin fit performance, and strap performance of NIOSH-approved N95 filtering facepiece respirators (FFRs) that have undergone various decontamination techniques. Based on the knowledge gained from these assessments, this report discusses important considerations when selecting techniques of FFR decontamination for occupational use. Findings from the NIOSH assessments indicate that FFR decontamination may have model-specific effects — the FFR manufacturer should be consulted before decontaminating any FFR.

The purpose of this assessment was to determine the effects of the decontamination process on the particulate filtration performance, manikin fit, and strap integrity of the respirator. It did not assess the reduction of the pathogen burden by the decontamination procedure.
