Replace your paper filters with the cilio Gold Filter. You no longer need to dispose of damp filter bags that can spill or tear on the way to the trash can. Instead of full bags, you get full aroma. While the adhesives in paper filters can leach out and affect the taste, the specially hardened and 24-carat gold-plated permanent filter perfectly highlights the aroma oils. Look forward to a complete coffee experience. You can also use the permanent filter in your coffee machine. Cleaning it under running water is quick and easy.
