Hahnemühle offers various filter media for personal and home-made protection masks for covering the mouth and nose. The filters are made from high-purity cellulose or synthetic fibers to filter coarse particles from air.
They can be set between other open fabrics or used as an interchangeable insert in the pocket of a sewn mask. The filter media differ in their thickness, elasticity and air permeability.
All filter papers can be processed by cutting, pleating and gluing. Hahnemühle offers you filter media in various roll and sheet formats to match your desired further processing.
