Maintenance Methods for Half-Masks, Full-Masks, and Filter Cartridges

I. Storage and Maintenance

Before use, inspect all parts of the mask for damage and replace any damaged parts.

Regularly check the filter cartridge and replace it when necessary.

Incorrect storage can shorten the life of respiratory protective equipment and reduce its effectiveness. Therefore, store the equipment in a clean plastic bag, in a personal toolbox or designated area, in a well-ventilated, clean, and dry environment.

II. Cleaning and Maintenance

Cleaning Instructions

Clean with soapy water or neutral detergent, avoiding organic or corrosive solvents.

Thoroughly rinse the mask in clean water, paying special attention to remove all soap residue from the exhalation valve to prevent corrosion. If possible, use tap water to repeatedly flush the exhalation valve.

Air dry the mask or dry it with a non-lint cloth. Accelerate drying with warm air below 40°C. Do not use an oven to dry, as it may cause aging of rubber components.

Maintenance

Conduct a routine inspection of the product monthly to check for scratches, dents, holes, cracks, notches, or deformation due to aging, heat, or contamination on the mask skirt, sealing area, headband, exhalation valve, and inhalation valve. Replace or contact the supplier for repair if any of these conditions are found.
