1, please pay attention to the purchase channel: it is recommended to purchase 3M products through 3M authorized dealers or the official flagship store of 3M Tmall () and the official flagship store of 3M Alibaba.
2. The smell of the mask will come from the mask material, such as the rubber material of the headband and the glue that sticks the nose clip. Because the raw materials of 3M products have passed strict toxicological tests, they are safe for human body, and those tastes are harmless. After opening the package and putting the protective mask in a clean and ventilated environment for a period of time, the taste will be greatly reduced.
Thank you for your attention to 3M and wish you a happy life ~
