Cambridge Mask masks are hand washable, and should then be hung dry. Do not machine wash or machine dry as this can damage the filters.
You can find the washing instructions are on the back of the packaging. Wash the mask by gently massaging with warm soapy water, rinse thoroughly and leave to hang dry. This will remove dirt, makeup and dust, however please note it will not extend the life of the filters. We do not recommend you to microwave the mask or wash the mask in a boiling water.
