1. How to store and maintain

a. Check the condition of each part of the mask before use, and replace damaged parts;

b. Regularly check the filter box and replace it if necessary;

c. The wrong storage method will shorten the life of the respiratory protection product and lose its protective effect; therefore, the respiratory protection product should be put into a clean plastic bag and stored in a personal toolbox or a designated location. The environment requires ventilation, cleanness and dryness.

2. Cleaning and maintenance

a. Cleaning instructions

Use soapy water or neutral detergent for cleaning, do not use organic or corrosive solvents;

Rinse the mask thoroughly in clean water, paying special attention to washing off all the soapy liquid on the exhalation valve to avoid corrosion. If conditions permit, please rinse the exhalation valve directly with tap water repeatedly;

Dry the mask by yourself, or dry it with a non-lint-free cloth; drying can be accelerated with hot air less than 40°C. Do not dry in an oven, so as not to cause aging of rubber components.

b. Maintenance

Routine inspection of the product is carried out on a regular basis every month to check whether there are scratches, dents, small holes, cracks, gaps, and defects caused by aging, heat or pollution If any of the above conditions are found, please replace it in time or contact the supplier for repair.
