- Made from biodegradable natural paper with four advantages: no bleaching, no smell, no adhesive, and no residue. It helps protect the coffee's original flavor and hygiene, and is safer and more secure to use. - Excellent Taste: Fine paper with uniform thickness removes most oils and coffee fines. These oils can make coffee taste bitter; filtering them helps preserve the coffee's original flavor. - V-shaped design: Conical shape directs water toward the center for a slower, more even extraction, yielding a mellower cup. Portable for travel, home, office, restaurant, etc. - Size and compatibility: A 200-count pack is enough for about half a year at one cup per day. Each filter has a small tab for easy handling. Fits most 2-4 cup coffee makers. - Environmentally friendly: Made from natural wood pulp, does not contain fluorescence or bleach. Safe for health and helps keep coffee pure and mellow.
