Fitting Characteristics of Eighteen N95 Filtering-Facepiece Respirators

Journal of Occupational and Environmental Hygiene, 2004
Four performance measures were used to evaluate the fitting characteristics of 18 models of N95 filtering-facepiece respirators: (1) the 5th percentile simulated workplace protection factor (SWPF) value, (2) the shift average SWPF value, (3) the h-value, and (4) the assignment error.

N95 Filtering Facepiece Respirator Deadspace Temperature and Humidity

Journal of Occupational and Environmental Hygiene, 2012
The 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 ...

Workplace Protection Factors for an N95 Filtering Facepiece Respirator

Journal of Occupational and Environmental Hygiene, 2007
This study evaluated the workplace performance of an N95 filtering facepiece, air-purifying respirator in a steel foundry. Air samples were collected inside and outside respirators worn by workers who were properly trained and qualitatively fit tested. For most workers, three or four pairs of air samples were collected on each of 2 days.
