    3 Use and maintenance
    3.1 When wearing a mask, check the air tightness of the mask first. Namely, after removing the drug filter box on the mask, the mask is worn upward from the chin, and the headband is adjusted appropriately. The sealing frame of the mask should be close to the wearer's face. When inhaling, no air leak occurs, which indicates that the mask has been airtight. Only when the drug filter box is installed properly, can it enter the poisoning area.
    3.2 After using the mask, the lenses, exhalation valves and inhalation valves should be kept clean, and the mask can be washed with water if necessary.
    3.3 If the mask is used in an infectious viral environment, it can be wiped, cleaned and disinfected with 1% peracetic acid disinfectant. The filter box should not be watered in order to prevent its failure. After disinfection with disinfectant, the mask should be wiped with clean water and dried before use.
