Petal filter bowls maintain a deep layer of filtration by circulating water from the center outward. Faster, smoother water flow is required to prevent unpleasant flavors from entering the liquid coffee. After a long period of research, CAFEC has finally achieved this ideal flower shape! Since the water doesn't stay in the colander, the same amount of water can be poured from the top as from the bottom. You can enjoy the best flavored coffee without unpleasant taste.
