Collection efficiency was evaluated for 10 respirator manufacturers' electrostatically-charged dust/mist filters challenged with eight sizes of latex spheres in a range representative of the silica aerosol used in National Institute for Occupational Safety and Health (NIOSH) certification tests. Minimum efficiency occurred at or below the smallest size of 0.102 microns. Appreciable differences were found in the performances of filters distributed by the 10 manufacturers. Filters produced by 1 manufacturer exhibited significantly lower collection efficiency than other filters tested; those produced by 2 manufacturers performed somewhat better than the others tested. Statistical evaluation of Weibull-transformed data using analyses of covariance and Tukey's significant difference test allowed classification of the 10 manufacturers into three performance categories.
在代表美国国家职业安全与健康研究所（NIOSH）认证测试中使用的二氧化硅气溶胶的范围内，对10家呼吸器制造商的静电尘埃/薄雾过滤器针对8种尺寸的乳胶球进行了收集效率评估。最低效率出现在0.102微米的最小尺寸或以下。发现10家制造商分发的过滤器性能存在明显差异。1家制造商生产的过滤器的收集效率明显低于其他测试过滤器；2家制造商生产的过滤器的性能略优于其他测试过滤器。使用协方差分析和Tukey显著差异检验对威布尔变换数据进行统计评估，可将10家制造商分为三个性能类别。
