  • Filter material, filter element, and method and device for producing a filter material
    Patent number: 9624605
    Abstract: A multi-layered, web-shaped filter material for a filter element may include a fleece layer, a cellulose layer, and a nanofiber layer arranged between the fleece layer and the cellulose layer. The nanofiber layer may be a coating of a nanofiber material disposed on the fleece layer. The cellulose layer may have an impregnation at least on a side facing the nanofiber layer.
