What is the use standard of medical masks

In view of the current quality of our living environment, we often choose to wear gauze masks when we go out. But what are the requirements for medical masks? What kind of standard does it have? What's the difference between it and ordinary gauze mask? Now let's understand.

The production of medical masks should comply with the technical requirements for medical gauze masks (GB 19083-2003). The masks can be divided into rectangular and close fitting types. They should be equipped with nose clips. They should have good surface moisture resistance and no irritation to the skin. When the air flow rate is 85L / min, the inspiratory resistance should not exceed 35mmh2o, and the particle filtration efficiency of the filter material should not be less than 95%. Medical gauze masks that meet N95 or FFP2 standards can also be selected.

In fact, for any gauze mask, in actual use, it should meet the requirements of filtering air impurities, so that the human body can be protected, which is more important.
