So how to distinguish the quality of disposable masks (non-medical)? Then look at it from the following three points:
1. The middle layer is burned with fire. If it is not easy to ignite, then it is possible to use melt blown cloth, because the ignition point of melt blown degree is relatively high and it is not easy to be ignited.
2. The thickness of the middle layer is normally 20 grams, which is thicker to the touch.

3. Whether the middle layer has undergone electret treatment. As mentioned earlier, the protection level of medical surgery is better after electret treatment. Viruses will be electrostatically adsorbed on the fiber surface. It can be taken apart for an electrostatic test. As shown below.

Finally, although the protection level and material supervision of disposable masks (non-medical) are not as strict as medical-grade masks, they also have a certain protective effect and can also be used in low-risk situations. Moreover, the price of disposable/protective masks (civilian) is lower than that of medical masks, and frequent replacement is also very important. In addition, many conscientious manufacturers that have passed the new approval to produce masks cannot be qualified to produce medical masks in the short term, but the quality of masks can also be guaranteed, which requires everyone to be patient and carefully screened. If you want to do comprehensive protection, the best way is to gather less and minimize going out.
