A new PPE CASE Report summarizes the first phase results of the NIOSH assessment of the Filtration Efficiency Performance of Non-NIOSH-Approved International Respiratory Protective Devices. Due to the potential to have these non-NIOSH-approved respirators used by workers in the United States, NIOSH designed a process to assess the particulate filtration performance. The goal of the assessment was to provide consumers of personal respiratory protection, and other interested parties, a point-of-use quantitative assessment of these devices.
