Anti pollution breathable dust mask to prevent dust inhalation. Includes four filters.
Made from Black cotton. The cotton mask can be hand washed with warm water and your choice of washing powder.
The mask comes with four filters included which are interchangeable. Simply slip the filter in the slot where the valve is on the inside of the mask and ensure loop holes are tightened over ears and the mouldable nose piece is pressed snug to the contours of your face. Each filter has a lifespan of approximately 48 hours of accumulated breathing use.
The valve does not need replacing.
