Notes:
Of course, N95 has the best filtering effect, but even the worst gauze mask can achieve nearly 80% protection rate for particles over 10 microns, that is, about one tenth of the diameter of hair. In a random experiment involving 2800 influenza personnel in the United States, there is no significant difference in the influenza infection rate between wearing N95 mask and medical mask, so don't care about the complicated masks type.
Due to different personal measuring techniques, there might be 1-3cm error of the physical. Thank you!
