Masks, as the last line of defense to reduce casualties and occupational disease accidents in safe production and medical work, their reliability and safety are of utmost importance. Therefore, in addition to the quality and functionality that customers pay more attention to, it is also necessary to consider more and more comprehensively, including whether the product performance changes after a period of use, etc., to ensure that the product is truly stable and reliable.

With the outbreak of the novel coronavirus in January 2020, people's attention to the epidemic is gradually increasing. Therefore, masks will become a necessity for people's daily self-protection. Mask manufacturers are also increasing and competition is increasing. The development of the civilian mask industry in China is relatively late, starting with SARS in 2003. In 2003, there was no standard for disposable medical masks, and the number and types of civilian masks were not enough. That is to say, in 2003, 3M company shifted from the industrial field to the civilian field, producing masks and selling them in China, occupying 90% of the domestic market. At that time, domestic masks did not yet have a brand, and brand benefits were not formed.
