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。 3 h3 |7 [* b) r, h' O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。 ' N7 w" I; B' p5 V! y! oN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。 8 s* |9 h7 h% O.

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. ) c' n, o l* b4 U* E6 s9 wNow 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. ; b* j1 q+ v2 g2 |0 NI 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. 9 I# S& d8 I4 Y& H% m' }. u7 r- l _Best wishes
