Simply the best!The Orion comes with a limited lifetime warranty and features our most powerful Ionizer with the patented  DARC system which represents the double action reverse cleaning system. This feature completely removes any scale from the electronic water cell. The MICOM control system optimizes the pH and ORP of your water and helps keeps your ionizer in top working condition. A new indicator light alerts you if service is needed on your ionizer. The Orion water ionizer shown above has a gracefully curved front with a gray silver color. All of the five controls for acid, alkaline, pure, the melody button and the power button to the left are conveniently arranged for fingertip control just below the display panel.
