PROBLEM TO BE SOLVED: To provide a water purifier capable of stably removing heavy metals such as lead or the like in tap water by simple constitution, preventing tap water from transiently becoming alkaline at an initial stage of the supply of water and suppressing the pH of purified water to a water quality standard of 8.6 or less to reduce an offensive smell component. SOLUTION: A water purifier is constituted of a raw water inflow part 2, a chelate resin part 6 removing metal ions flowing in from the raw water inflow part 2, the hydrogen type cation exchange resin part 9 removing cations disposed on the downstream side of the chelate resin part 6 and a purified water discharge part. |
