Features: Detachable design: The cup can be removed for easy cleaning and portability. Oxygen-rich design: Hydrogen is produced through micro-electrolysis. Higher mineral content in water enhances the electrolytic effect, resulting in increased hydrogen concentration. Stable and portable: Advanced electrolysis technology promotes efficient integration of hydrogen into water, delivering high hydrogen concentration with consistent stability. This portable hydrogen water generator provides healthier water. Ideal for producing hydrogen-rich water anytime and anywhere. Safety: Utilizes hydrogen-oxygen separation technology, capable of electrolyzing pure water to enrich hydrogen content without filter rods. Effectively reduces ozone and chlorine levels. Convenient for on-the-go use: Enjoy the benefits of hydrogen-enriched water wherever you are, supporting your health journey. Note: 1.
