就我所知,N95口罩确有多种型号,但主要是由外形,过滤层的用料和不同厂家等因素决定的。' Q( ~4 `- N% c' W! v/ s, K
其主要的参数是NIOSH(美国职业安全卫生研究所)的参数:过滤效能要至少达95%效能。8 n: g6 b1 f0 c
N为过滤非油性颗粒的。由于生物性微粒多属非油性颗粒因此需使用N级。而N95级即表示可防护非油性颗粒过滤效能为95%。外形为高周波压制的碗型。9 F* Z' n3 _4 F
我进口罩的厂家有美国的NIOSH和欧洲的CE认证,是非典时期生产防菌型口罩的主要厂家。每年的出口额是1200万美元以上。质量上可以放心。- `, c T" H& j. d5 }+ G
说实话,我进这口罩的心里是很矛盾的。当然是希望能卖得出去,但又希望情况不要坏到非使用口罩不可的程度。
Sorry everyone, I did not come to this website for quite a while. 7 D4 [2 \ c8 I; S x/ T. sNow I am applying the established license for importing the face mask. This is the government requirement for importing class 1 medical materials, which including face mask. This was a surprise for me. I have discussed that with several government departments for the license and finally found a clue. The whole process would take 1 to 2 months. That means my masks ( I have already paid money) have to be stored in a Chinese factory until I obtain the license.$ K& j8 t& c1 N+ z k
I am so sorry for this unexpected process. If anyone needs the face mask in the following one month, please try to buy them in a drugstore or other places. * U5 h5 n/ N, }; j. H
