Purify is a water-purification faucet. It uses a coaxial dual-control valve core to dispense purified water and bubble water. The use of the composite filter element breaks the traditional installation method of the faucet. No external filtering machine is required, and the installation is more convenient. Purify has a time-memorized ring to remind users to replace the filter core. The cold-start technology makes it more energy efficient. It is also offered in many finishes to meet the needs of different kitchen styles.
