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

March 2020
NPPTL Report Number P2020-0103

NIOSH found that 256 of 258 N95 filtering facepiece respirators stockpiled at Facility Three 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 details the inhalation/exhalation resistance and filtration performance of N95 filtering facepiece APRs collected from Facility Three of Ten. This facility is a county stockpile facility.
