The weather in Shanghai is seriously polluted. What brand of mask do you want now?

Do you know how to wear a mask correctly? First of all, wash your hands to avoid dirty hands polluting the inside of the mask. Stick the mask on your face, nose and mouth, and hang the ropes at both ends on your ears with your hands. At the same time, pull the folds of the mask up and down with your hands to make the mask completely cover your mouth, nose and chin.

3M, Green Shield, Honeywell, Youweisi, Baiyuan, Kimberly-Clark, Yangpu, PuraVation, Puweixin, Steady Win and Chaomei CM…… are all very good. I suggest you go.
