PPE CASE – Performance of Stockpiled Air-Purifying Respirators, Facility Four of Ten: Inhalation and Exhalation Resistance and Filtration  Efficiency Performance										Related Pages
										**March 2020**
**NPPTL Report Number P2020-0104**NIOSH found that 540 of 574 N95 filtering facepiece respirators and P95 filters stockpiled at Facility Four that were 8-12 years old maintained their inhalation and exhalation resistance and filtration performance in accordance with NIOSH performance standards.Cover page for PPE-CASE-P2020-0104
In 2017, NIOSH established a PPE Stockpile Partnership consisting of 1) federal entities and stockpiles; 2) state, county, and city stockpiles; 3) hospital-related stockpile entities; and 4) a manufacturer trade association to inform the design and execution of an empirical study to evaluate stockpiled air-purifying respirators. NIOSH obtained samples of PPE from geographically dispersed stockpiles with varying storage conditions.
**This report details the inhalation/exhalation resistance and filtration performance of N95 filtering facepiece respirators and P95 filters collected from Facility Four of Ten. This facility is a state stockpile facility.**Performance of Stockpiled Air-Purifying Respirators, Facility Four of Ten: Inhalation and Exhalation Resistance and Filtration Efficiency Performance [PDF – 3 MB]Suggested Citation
