I'm selling this item because I bought it but never used it. I threw away the box. Caffe Hat White Ceramic Coffee Filter/Dripper - No Paper Filters Needed This is a ceramic coffee filter that doesn't require paper filters. The coffee filter is made of porous ceramic, and the far-infrared effect and microscopic holes remove chlorine odor and impurities from the water, allowing you to enjoy a mellow and easy-to-drink coffee. It can also be used as a water purifier, so it's recommended for those who have a habit of drinking water at home. Although it is new, it has been stored by a private individual, so please consider purchasing it with your understanding. mm
