Feature: 1. Micro‑electrolysis generates hydrogen for three minutes. The higher the mineral content in the water, the electrolysis effect is more strong and the higher the hydrogen content. 2. Electrolysis technology promotes the stable combination of hydrogen and water, with high hydrogen concentration and good stability. 3. It only takes 3 minutes to quickly electrolyze, change water quality, helps to improve metabolism and nutrient absorption. 4. SPE hydrogen‑oxygen separation technology replaces filter rods with higher hydrogen content. It can electrolyze pure water, add hydrogen that is more beneficial to health, and remove harmful ozone and chlorine. 5. 1.5 liters of water per day is equal to the antioxidant value of hundreds of fruits and vegetables. Hydrogen-rich water can reduce toxic free radicals, thereby reducing human aging and strengthening immunity.

Monitors are not calibrated same, item color displayed in photos may be showing slightly different from the real object. Please take the real one as standard.3. The small white ball at the bottom plays a role of purifying water, which is harmless to the body and does not need to be dug out.4. Since a large amount of water is produced every day, it is reminded to re‑tighten the bottom of the cup after receiving the product to prevent water leakage.5. Do not clean the bottom of the cup when cleaning, otherwise the charging will stop.
