Regular replacement
Dust masks accumulate a significant amount of dust and bacteria after prolonged use, thus necessitating regular replacement. It is generally recommended to change them daily, or immediately when the mask becomes contaminated or damp.
Avoid Water Washing
The filter element of dust masks is not washable; washing it can damage its filtering performance. Therefore, when cleaning the mask, it should be avoided to directly rinse the filter element with water.
Storage Precautions
Dust masks should be stored in a dry, well-ventilated area, away from direct sunlight and high temperatures. Additionally, they should be kept away from harmful substances to prevent contamination.
