The CB-EC filter element, made of compressed activated carbon, improves the taste and odor of water by reducing the levels of chlorine, pesticides, bacteria, and other organic and oxidizing substances in the water. The recommended service life of the cartridge is 3–6 months. To protect the cartridge surface, it is recommended to use a pre-filter (5 µ). The cartridge is not reusable. It is intended for filtering cold water for household use and drinking.
