普通的N95口罩：N95 Respirator Occupational (including medical) use. Reduces wearer’s exposure to particles including small particle aerosols and large droplets (all non-oil aerosols).
医用的N95口罩：Surgical N95 Respirator Can be used in any occupational setting where an N95 respirator is appropriate. Medical use where a sterile field needs to be maintained. Reduces wearer’s exposure to certain airborne particles (all non-oil aerosols) and provides a barrier to splashes and sprays.

但我再次认真看了一下cdc关于N95口罩的介绍，只想说Home Depot或者Lowe's里的N95口罩（型号以8打头）都能用。如果你们村里还有货就赶紧买。

Surgical N95的介绍

飞沫不是水。上面说的防水是指液体喷溅，比如病人血喷出来。
no，普通外科口罩最大的问题是不密闭，空气中飞沫会从口罩边缘被吸入，只能防飞溅和部分飞沫
当然口罩即使医用N95也不是100%的，所以：
远离病毒源>>医用N95>工业N95>普通外科口罩>裸奔
是这样的，其实level3也不是特别有必要，非外科手术情况level1，level2也可以用
现在邮寄都怕丢。我们诊所有一般外科口罩，但不是很多了。也不能都拿回家
供应商那里说1860三月才有货。还黑心的涨价了
这个一般老百姓戴是吓人
医院还不能用这种是不？不是医疗用的。是工业用
这种是P100过滤度，99.97%，连气化油都能防的，比医用级别更高，是防化级别。
觉得不必要，就算100%，从眼睛，飞沫降到皮肤上又接触传染等概率也不小
所以还是那句话，最好的100%防护就是远离感染源，口罩等就是没办法的办法，千万不要以为戴了就刀枪不入万无一失了
如果国内不好转又不得不回国时候 考虑买这个。有人用过没？憋的慌不？
原则上是可以的,和医疗的N95比区别只是不防水
但是,能不能用不是你说了算,是接收单位敢不敢用. 3M 的1860 是国内也有的也接受的,所以没问题.
这才是担心的地方.
大小不合适漏气吧
戴上后每次都必须检查边缘是否漏气，办法是用手捂着边缘用力吹气，如果感觉手上有风，就是漏气了，要调整
这边在纠结N95的微孔能不能比病毒更小，那边边缘有大缝漏气，那才是笑话了
长什么样的？
就是我给你贴的那个
哦谢谢，感觉那个口罩很好👍
现在也买不到1860了吧。8210不是说医院也不让用。不够标准

正好ebola的时候买了点p100，回头可以从箱子底下翻出来了
Mark. Thanks for sharing/
为什么要扯下来？
非常同意。已经无数次播报说过普通生活一般的医疗口罩就可以了，除非去病毒源集中的地方比如医院或者飞疫区的飞机最好戴N95。警惕与自我保护是对的，但是过分paranoid也没必要
这个外面带不出去吧，我用过，不算憋气，但也不舒服，带着二三十分钟没问题，夏天带着应该很难受就是。
