Feature: 1. 3 Minutes of micro‑electrolysis hydrogen production process, the higher the mineral content in the water, the stronger the electrolysis effect, and the higher the hydrogen content. 2. It takes only 3 minutes to quickly electrolyze, change the water quality, and often accompany you. 3. 1.5L water per day, equivalent to the antioxidant value of hundreds of fruits and vegetables. 4. Hydrogen‑rich water can reduce toxic free radicals, thereby reducing the body's aging and enhancing immunity. 5. The electrolysis technology promotes the stable combination of hydrogen and water, and has the characteristics of high hydrogen concentration and good stability. 6.
