Melitta has become known as the standard in coffee filters. Known for their versatility for a number of brewing devices (Including the Bee House Dripper as well as the Clever Dripper), Melitta produces durable and high quality filters that are affordable. When you buy Melitta filters, you are also helping save the world. We're being serious, as Melitta is a proud partner with the Global ReLeaf program, making an annual donation to support the national education and action campaign aimed at improving the earth's environment one tree at a time.
