An investigation of filtration performance of different filtering facepiece respirators (FFRs) found high disparities between FFRs purchased by healthcare establishments. NIOSH-approved certification offered good efficiency compared to non NIOSH-approved FFRs. Furthermore, inspecting FFRs visually was not helpful in determining if the product was counterfeit or had defects. Brochot et al. (Oct 30, 2020).
