Simulated Workplace Performance of N95 Respirators
AIHA Journal, 1999During July 1995 the National Institute for Occupational Safety and Health (NIOSH) began to certify nine new classes of particulate respirators. To determine the level of performance of these respirators, NIOSH researchers conducted a study to (1) measure the simulated workplace performance of 21 N95 respirator models, (2) determine whether fit-testing

N95 Filtering Facepiece Respirator Deadspace Temperature and Humidity
Journal of Occupational and Environmental Hygiene, 2012The objective of this study was to determine the levels of heat and humidity that develop within the deadspace of N95 filtering facepiece respirators (N95 FFR). Seventeen subjects wore two models each of N95 FFR and N95 FFR with an exhalation valve (N95 FFR/EV) while exercising on a treadmill at a low-moderate work rate for 1 and 2 hr in a temperate ...

Thermal Burden of N95 Filtering Facepiece Respirators
The Annals of Occupational Hygiene, 2012Increased thermal perceptions that affect comfort are a leading reason for intolerance to wearing respiratory protective equipment. Despite their popularity and use for decades, relatively little is known about the thermal burden imposed by the use of N95 filtering facepiece respirators (FFR) at normal work rates. Twenty healthy subjects exercised at a

Review of the Effect of Continuous Use and Limited Reuse of N95 Respirators on Respirator Fit
Journal of the International Society for Respiratory Protection, 2021Background: Coronavirus disease 2019 (COVID-19) has led to severe shortages of filtering facepiece respirators (FFRs). As a result, extended use, limited reuse, and FFR decontamination have been utilized to extend the life of single-use FFRs. Although some studies have raised concerns that reuse could affect the FFR’s ability to form a seal, no ...
