Workplace Protection Factor Study

A new study published in the Journal of Occupational and Environmental Hygiene found that a quarter-facepiece elastomeric respirator effectively protects against airborne particles in simulated workplace conditions. The study, conducted by a team of researchers from the University of Illinois at Chicago School of Public Health, supports increasing the assigned protection factor (APF) for quarter-facepiece respirators, a class ignored by most manufacturers over the last 40 years.
