Thank you for viewing! ☺︎ • Brand new, unused (operation not confirmed) ※ Since it is brand new and unused, we cannot answer detailed questions. 【Replacement product equivalent to the genuine product】 Fully upgraded in terms of materials, adopting more advanced high-density activated carbon, carefully selected domestic filter materials, and a six-layer filtration system using filters to remove over 80% of impurities from tap water. While achieving the same usage period as the genuine product, it effectively blocks finer impurities and pollutants. The new material is superior in corrosion resistance and pressure resistance, maintaining stable performance even under harsh environments such as high temperature and humidity. By reducing resistance during fluid passage and improving flow efficiency, it achieves both high-efficiency filtering and energy saving. It has been tested by authoritative institutions and complies with Japanese international safety standards, making it highly reliable and safer. 【Compatible Models】 Water purifier models TK-CJ14, TK-CJ24, TK-CJ23, TK-CJ22, TK-CJ21, TK-CJ12, TK-CJ11, TK-CJ01, and compatible main unit model numbers TK-CJ01C1, TK-CJ21C1, TK-CJ22C1, TK-CJ23C1, TK-CJ23C2. 【Japanese 6-Layer Filter Materials】 One filter can replace 2000 2-liter plastic bottles. The filter needs to be replaced once a year. A two-stage mode of raw water and purified water can be selected to extend the filter life. ABS resin, activated carbon fiber (ACF) + granular activated carbon, hollow fiber membrane, hydrophilic non-woven fabric, and technology not only enhance the purity of water but also improve the taste and flavor. Transforms ordinary tap water into refreshing water like high-quality mineral water. 【Removes 19 substances including PFOS and PFOA】 Removes impurities: The tap water filter system adopts advanced carbon block technology, removing the taste and odor of chlorine and reducing multiple harmful substances contained in drinking water. Substances to be removed: Free residual chlorine (chlorine), CAT (pesticide), PFOS and PFOA, turbidity, 2-MIB (musty odor), iron (particulate), chloroform, soluble lead, aluminum (neutral), total trihalomethanes, 1,2-DCE, bromodichloromethane, benzene, dibromochloromethane, geosmin (musty odor), bromoform, phenols, tetrachloroethylene, trichloroethylene 【Easy Installation】 Easy to install, no special tools or skills required. 217-1350
