Filtration testing results.

Initial filtration performance of 0.26 μm (mass mean diameter) NaCl at a flow rate of 85 L/min is reported. Filtration efficiency and pressure drop shown for the test group masks is an average of the two masks of each type tested. Variation between the two samples was minimal. Testing performed with a TSI Inc. Automated Filter Tester 8130A.本数据集报告了流量为85 L/min时，粒径为0.26 μm（质量平均直径）的氯化钠（NaCl）的初始过滤性能。受试组口罩的过滤效率与压降数据，为每种测试类型的两只口罩的平均值，且两组样品间的差异极小。本次测试采用TSI公司（TSI Inc.）的8130A型自动过滤测试仪完成。
