老婆给我看微信某师奶的传言：打电话去3M求证了 3M N95 8210只防工业粉尘，不防病毒。
这与我过去两个月从某些我信得过的博客所获得的零碎关于3M N95的资讯不同，而且我一向对师奶科技抱有严重戒心。
本着大胆假设，小心求证的精神，很快就得Google出最权威的一手资料。

Surgical N95 vs. Standard N95 – Which to Consider? @ https://multimedia.3m.com/mws/media/1794572O/surgical-n95-vs-standard-n95-which-to-consider.pdf
Therefore, if a healthcare facility is prioritizing respirator use – due to, for example, limited supply during a health emergency
– they may want to consider prioritizing use of surgical N95 respirators for those healthcare workers requiring respiratory
protection while performing surgery or other tasks that may expose them to high pressure streams of bodily fluid or
conducting work in a sterile field. For other workers who will not be performing such surgical procedures or do not need to
maintain a sterile field, a standard non-surgical N95 (or equivalent) respirator can be worn to help reduce those workers’
exposure to patient-generated airborne viruses and bacteria.
各位看官，怎看？
