PPE CASE – Performance of Stockpiled Air-Purifying Respirators, Facility One of Ten: Inhalation and Exhalation Resistance and Filtration Efficiency Performance

March 2020
NPPTL Report Number P2020-0101

NIOSH found that 344 of 344 N95 filtering facepiece respirators stockpiled at Facility One that were 8-11 years old maintained their inhalation and exhalation resistance and filtration performance in accordance with NIOSH performance standards.

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 APRs. NIOSH obtained samples of PPE from geographically dispersed stockpiles with varying storage conditions.

This report describes the inhalation/exhalation resistance and filtration performance of N95 filtering facepiece APRs collected from Facility One of Ten. This facility is a state stockpile facility.
