Abstract
The efficacy of powered air-purifying respirators, surgical masks, dus t/mist respirators, and high-efficiency respirators were tested,vith a biological aerosol under simulated breathing conditions. Protective a bility ranged from 67 to 99.95%. The majority of penetration in negati ve-pressure respirators occurred at the face-mask interface rather tha n through the filter material.
