(3) membrane filter: used primarily to remove bacteria, colloids and other organic molecules in water, is generally used for cycle 1--2 years.
(4) post carbon: adsorbed further main color, odor, taste improving water quality, typically using period 12 months.
(5) RO membrane filter: used primarily to remove bacteria, viruses, heavy metals, organic compounds and inorganic salts in the water, the cycle generally used to 2 - 3 years.
(6) anion mineralization filter: major release of two dozen trace elements needed by the human body, the general use of 1-year period - 2 years.
(7) softening resin filter: mainly used to remove calcium and magnesium ions, reduce water hardness, do not meet the levels of demand, reduction in the professional regeneration salt to be used repeatedly, the general cycle 5-
