Product Description Patent for manufacturing filters in Japan and the United States (technology to remove coffee oil and create microscopic holes) and patents related to molding. The Arita-yaki Cera Filter can be used not only for coffee but also for water, tea, and sake. THREE RIVERS Co., Ltd. manufactures the "Arita-yaki Cera Filter," a coffee filter with a unique patented technology in Japan, while preserving the traditional Arita-yaki. The "Arita-yaki Cera Filter" is a magical tool that mellows the taste simply by passing a beverage through it. It is made of a material called "porous ceramic" with countless holes of several microns in size, and the W effect of the ceramic's power and far-infrared rays removes chlorine odor and impurities from water. It removes impurities with an invisible fine mesh, suppressing bitterness and harshness, and allowing you to enjoy a mellow drink. It can be used for a wide range of beverages, including coffee, tap water, green tea, shochu, sake, and wine, and can be used in all kinds of everyday situations. What is the difference from paper filters used when brewing coffee? In fact, paper filters can sometimes absorb the original flavor and oil of the beans excessively. However, this Arita-yaki Cera Filter removes bitterness while extracting the flavor and oil without absorbing them. One of the attractions is the eco-friendly aspect of "not needing to use paper every time you brew coffee." It can also be used for water, tea, sake, and other beverages besides coffee.
