The reusable antivirus mouth mask comprises a sterilization paper layer, a graphene-based filter material layer, a solid alkali layer and a non-woven fabric layer which are sequentially stacked from outside to inside. Wherein the AOP-KF solid alkali has strong effect of killing virus and bacteria, but does not produce toxic effect on animal and plant organisms. The reason is that the cell structure of bacteria is quite different from that of higher animals and plants, bacteria are prokaryotes, and animals and humans are eukaryotes. Most enzyme systems in prokaryotic cells are distributed on the near surface of a cell membrane and are easy to attack, while enzyme systems of eukaryotic cells are deep into the cells and are not easy to attack by AOP-KF solid alkali and cannot cause damage to the cells. In addition, higher animals and plants not only have a multicellular complex organic structure, but also form a protective system against various oxidants in vivo. Therefore, the antibacterial agent has no harm to animals, plants and human bodies, and has broad-spectrum antibacterial property and high safety. The functionalized graphene has extremely high specific surface area and contains abundant adsorption sites such as a large number of functional groups and defects. The structure of the functionalized graphene sheet layer is compounded on the framework of the base material by adopting a unique compounding technology to form the filter material with a three-dimensional multistage porous structure, so that the multistage filtering effect is achieved.

On the other hand, the air door is formed, and has a switching effect, wherein the air door is opened in a positive direction when air is discharged and is opened in a negative direction when air is introduced. Due to the extremely small pore size of graphene membranes (a significant fraction of pores are smaller than one micron), and the complete longitudinal coverage, which is equivalent to multi-layer filtration, the graphene membranes block most of PM2.5, even PM1 (since PM1 is not well known, detection means at home and abroad are almost none, but particles which can enter blood vessels). Due to the above characteristics. The product fundamentally changes the principle that most masks in the market depend on electrostatic adsorption, and completely utilizes the interception and adsorption method to block PM 2.5.
