Medical masks belong to the second category of medical equipment, while civilian masks, which are masks that are not marked with the word "medical", are not. This will have a lot of requirements for manufacturers, at least they must have a license and registration certificate for the production of medical devices. In addition, the production of medical masks also has requirements for the production environment. Generally, it needs to be produced in a 100,000-level workshop, and it needs to have the ability to identify microorganisms. So the word medical on the mask is not something you want to add, you can add it if you want~
