老婆給我看微信某師奶的傳言：打電話去3M求證了 3M N95 8210隻防工業粉塵，不防病毒。

這與我過去兩個月從某些我信得過的博客所獲得的零碎關於3M N95的資訊不同，而且我一向對師奶科技抱有嚴重戒心。

本着大膽假設，小心求證的精神，很快就得Google出最權威的一手資料。

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.
