Pinyon Products Cloth Coffee Filter Cone Sized 2 are an awesome alternative to paper filters. They’re made of a naturally mildew resistant 55% hemp, 45% cotton blend. You can compost your used grounds, and then simply rinse the filter out and lay it flat to air-dry. Don’t wash them with soaps or detergents, the hemp helps keep them naturally clean! And as an added bonus, they’re Canadian made in White Rock, B.C.
