nAccoding to the material and protective levels, you should choose your own N95 masks properly

In addition to good filter materials, protective masks should also have good shape design and nose clip design: the better the mask fits the wearer’s face, the better the protection effect, which can prevent pollutants from the edges of the mask, especially the nose wings The gaps on both sides enter the mouth and nose. Therefore, when wearing a mask, the nose clip at the bridge of the nose should be pressed tightly, and the length of the mask strap should be adjusted appropriately so that the mask fits the face as much as possible.

When wearing medical masks, choose the appropriate level type according to the type of pollutant transmission and risk, not too high or too low. Although medical protective masks with high protection levels have better protective effects, because of the high level of filter material, good adhesion, and higher respiratory resistance, wearing them for a long time will increase the respiratory burden and cause breathing difficulties and other discomforts.

Medical surgical masks and medical protective masks can block the pollution caused by blood and body fluid splashing, but if you really need to block the pollution of airborne particles and pathogenic microorganisms, please choose to wear medical protective masks.
