Abstract
The efficacy of powered air-purifying respirators, surgical masks, dust/mist respirators, and high-efficiency respirators were tested with a biological aerosol under simulated breathing conditions. Protective ability ranged from 67 to 99.95%. The majority of penetration in negative-pressure respirators occurred at the face-mask interface rather than through the filter material.
摘要
动力空气净化呼吸器、外科口罩、防尘/雾口罩和高效呼吸器在模拟呼吸条件下用生物气溶胶进行了测试。防护能力范围为 67%至 99.95%。负压呼吸器中的大部分渗透发生在面罩接口处，而不是通过过滤材料。
