颗粒净化器已在一般环境和工作场所中使用。尽管有经过认证的工人呼吸机，但世界各地对口罩没有严格的规定。本研究的目的是使用韩国食品药品监督管理局（KFDA）[类似于欧盟（EU）方案]和国家职业安全与健康研究所（NIOSH）方案评价各种口罩类型的过滤效率，并比较测试结果。我们使用TSI 8130自动过滤测试仪对四种类型（防黄沙、医疗、检疫、一般）共44个口罩品牌和口罩进行了测试。通过面罩类型观察到渗透和压降的广泛变化。根据KFDA方案，所有受试面罩的总体平均渗透率和压降分别为35.6 +/-34.7%，2.7 +/- 1.4 mm H2O，根据NIOSH方案，分别为35.1 +/-35.7%，10.6 +/- 5.88 mm H2O。所有测试的检疫口罩均符合韩国食品和药物管理局6%的标准。成人和儿童防黄沙口罩的九分之六和七分之四分别满足20%的标准。医用口罩、普通口罩和口罩对呼吸道气溶胶几乎没有保护作用。
Particulate respirators have been used in both general environments and in the workplace. Despite the existence of certified respirators for workers, no strict regulations exist for masks worldwide. The aims of this study were to evaluate the filter efficiency of various mask types using the Korean Food and Drug Administration (KFDA) [similar to the European Union (EU) protocol] and the National Institute for Occupational Safety and Health (NIOSH) protocol and to compare the test results. We tested a total of 44 mask brands of four types (anti-yellow sand, medical, quarantine, general) and handkerchiefs with a TSI 8130 Automatic Filter Tester. A wide variation of penetration and pressure drops was observed by mask types. The overall mean penetration and pressure drop of all tested masks were respectively 35.6 +/- 34.7%, 2.7 +/- 1.4 mm H2O with the KFDA protocol, and 35.1 +/- 35.7%, 10.6 +/- 5.88 mm H2O with the NIOSH protocol. All tested quarantine masks satisfied the KFDA criterion of 6%. Six-ninths and four-sevenths of the anti-yellow sand masks for adults and children satisfied the criterion of 20%, respectively. Medical masks, general masks, and handkerchiefs were found to provide little protection against respiratory aerosols.
