English term
N95 respirator
The Centers for Disease Control and Prevention (CDC) does not recommend that the general public wear N95 respirators to protect themselves from respiratory diseases, including coronavirus (COVID-19). (FDA)
Supplies of N95 respirators can become depleted during an influenza pandemic (1-3) or wide-spreadoutbreaks of other infectious respiratory illnesses. (Center for Disease Control)
Importantly, the study showed that N95 respirators significantly reduced the risk of bacterial infection by 62% compared to no mask, and by 46% compared to surgical masks. (ISG)

N95口罩
N95型口罩是NIOSH(美国国家职业安全卫生研究所,National Institute for Occupational Safety and Health)认证的9种颗粒物防护口罩中的一种。 (Baidu)
N95口罩和KN95口罩都是很火的口罩,这些名称方面的差异,怎么理解? 奉成高:两种名称的差异,其实均是颗粒物防护口罩,只是对应的标准不同。KN95是中国标准GB 2626中的概念,N95是美国联邦法规中的概念,二者测试方法类似、主要技术参数基本相同,简而言之都要求非油性颗粒物的过滤效率达到95%以上。 (PR Newswire)
3M是美国最大医用防护口罩生产商,尤以生产N95口罩闻名。随着新冠肺炎疫情在美国蔓延,美国全国各地不少医院遭遇医用防护用品紧缺。 (人民网)
N95呼吸器
N95口罩其实属于呼吸器 (respirator),呼吸器是一种呼吸防护设备,在设计上相较于普通口罩来说贴合面部更加紧密,可以非常有效地过滤空气中的颗粒物。其中,N表示Not resistant to oil, 可以用于防护非油性悬浮颗粒;95的意思是过滤效率大于等于95%,表明经过仔细测试后,这种呼吸器可以阻挡至少95%的非常小的(0.3微米级别)测试颗粒。 从设计上,如果按照对佩戴者自身的防护能力优先级排名的话(从高到低):N95口罩>外科口罩>普通医用口罩>普通棉口罩。 如果佩戴正确,N95的过滤能力是要优于普通口罩和医用口罩的。但是,即使佩戴完全符合要求,也无法100%消除感染疾病或死亡的风险。 KN95是中国标准GB2626-2006中规定的级别之一 N95是美国标准42 CFR 84中规定的级别之一。 这两个级别的技术要求、测试方法等基本一致, 都是对应标准下过滤效率达到95%。 (N95口罩其实属于呼吸器 (respirat)
