The wearing feeling after the water-free disinfection is poor, the user will wish to reuse the mask is objectively reduced, the reusable mask is prevented from exerting the use efficiency, and the practical popularization difficulty is caused.

In addition, after the mask is used, when the filter element is replaced, the hand needs to stretch into the middle of the interlayer of the mask body to extract the filter element, so that the hand is inevitably in contact with the mask in a large range, and the hand of a user is polluted.

Finally, some masks with built-in filter elements do not support integral washing, and can only be sterilized in a water-free sterilization mode, such as ultraviolet or ozone or medical alcohol sterilization. Although the anhydrous sterilization can kill viruses and bacteria, the odor caused by the enrichment of external pollution sources or the contamination of oral and nasal body fluid cannot be removed. The wearing feeling after the water-free disinfection is poor, and the willingness of the user to use repeatedly is reduced.
