  • For washing, we recommend that the mask be washed by hand in running cold water with mild soap. Also, the mask should not be washed in a washing machine. Machine wash can cause damage to the structural integrity of the micro-fibers of the melt blown filter media. The mask should only be hung dry without wringing

This means that the filter media that is used in the mask has been clogged due to impurities, dust particles etc that are filtered as you breathe through the mask
