美國 CDC 對於武漢肺炎建議至少使用 N95。
高標自然就看個人預算。
不過是否只能使用 surgical N95,我就不清楚了,
反正我也不是醫護人員。
(3M 18XX系列 N95 口罩才是 surgical)
N95口罩在髒空氣環境下,壽命可能縮短至1/2,
也就是8小時/2=4小時。

Respiratory Protection
Use respiratory protection (i.e., a respirator) that is at least as protective as a fit-tested NIOSH-certified disposable N95 filtering facepiece respirator before entry into the patient room or care area. See appendix for respirator definition.
