Japanese-made faucet water purifier with a purification capacity of approximately 4,000 liters, removing 17 substances. - Model Name: TK-CJ12-W - Purification Capacity: Approximately 4,000 liters - Substances Removed: 17 substances - Country of Manufacture: Japan Thank you for viewing. This is a water purifier that attaches to a faucet. The main body and cartridge have a lifespan of approximately 2 years. There is some aging (yellowing) on the plastic parts of the main body, so there is a sense of use. I believe the adapters are likely all included, but I will ship everything shown in the photos together. I am selling this due to moving.
