[Product] WELTEC Weltec Water Purifier with Hydrogen Water Generator AUQA OASIS H2 Aqua Oasis H2 Model: AC-KN6000H Color: Red The electrolysis method, which is commonly used in hydrogen water servers, passes water around the electrodes and converts the water into hydrogen water through electrolysis. The separation generation method separates drinking water and water for electrolysis, and generates hydrogen by dissolving it in drinking water. Since the electrodes do not directly touch the drinking water, there is no need to worry about the electrodes dissolving, and there is no change in pH.
