From manufacturer website: “Tyent water ionizers are small appliances that adjust the pH level of your tap water to make it more alkaline or acidic, and in the process, infuse it with molecular hydrogen—a colorless, odorless, and tasteless gas that’s packed with antioxidant benefits.

The process that converts tap water into hydrogen-rich alkaline water is called electrolysis. In water ionizer machines, water is run over positive and negative electrodes, which ionizes the water. 

The ionized water is then separated into alkaline water and acidic water as it passes through membranes. The membranes are able to repel the water now that it has been “charged” into positive and negative ions. An increase in negatively charged ions creates alkaline water while an increase in positively charged ions creates acidic water. 

Part of the electrolysis process involves the water being split into its components: hydrogen and oxygen. The oxygen is expelled and the hydrogen bubbles are dissolved into the water. With a Tyent water ionizer you can access maximum levels of molecular hydrogen—and maximum health benefits.”  Dimensions: 14.5” H x 11.75” W x 5.75” D. 

Appears to be in good used condition. There are signs of wear throughout and thorough cleaning is recommended. Signs of wear include some minor oxidation along exterior metal elements. See photos for more details. Tested and powers on as it should.
