Biodegradable natural paper Our coffee filter is made from biodegradable natural paper. It offers four advantages: no log bleaching, no smell, no adhesive, and no residue. It helps protect the original taste of coffee and supports hygiene, while being safer and more secure to use. Excellent taste Fine paper with uniform thickness removes most of the oils and coffee particles. Those oils can make coffee taste bitter, so removing them helps preserve the coffee’s original flavor. V-shaped design The conical design slows water flow to the center, producing a mellower cup as water penetrates gradually. Easy to carry and well suited for travel, home, office, or restaurant use. Compatibility and capacity Based on one cup of coffee per day, 200 count lasts more than half a year. Each filter sheet features a small ear for easy handling. Fits any 2-4 cup coffee maker. Safety and environmental friendly Made of natural wood pulp, it does not contain fluorescence or bleach, is safe for health and environmentally friendly, and keeps coffee pure and mellow.
