Contents: 1 main pitcher, 1 ZERO filter, 1 ZERO gauge (TDS meter) Unused, but the box has been opened and has scratches. The unique 6-layer filter removes solid particles, heavy metals, inorganic substances, bacteria, and removes residual chlorine and odors from water. It can be easily produced with tap water, reducing the need to buy water, waste, and storage space. It can be used for multiple purposes, such as drinking water, cooking, beauty, and cleaning. It enhances the natural flavor of Japanese tea leaves and the richness and umami of coffee beans. Miso soup and simmered dishes also allow water to penetrate vegetables well, allowing you to directly taste the ingredients. Because it removes minerals, it is also suitable for baby formula and pet water. You can always check the condition of the water you are using with the ZERO gauge (TDS meter).
