SPE membrane technology: with solid polymer electrolyte membrane technology (SPE) that separates hydrogen and oxygen in the water and then releases the hydrogen back into the water to produce hydrogen enriched water. Hydrogen rich water: The hydrogen water bottle is not only a water container, but a generator that converts normal water into hydrogen-rich water, known for its potential antioxidant and health benefits. Large capacity: With a large capacity of 1.5 litres, the hydrogen water bottle can produce an abundant amount of hydrogen-rich water in one filling to meet your daily hydration needs. 【Benefits of Hydrogen Absorption】: Improves athletic performance, reduces fatigue and improves exercise efficiency, also helps promote metabolism, improve sleep quality and promote overall well-being. Easy to use: the hydrogen generator is portable and user-friendly. Simply add a suitable water source, activate the generator, and within moments you have hydrogen-enriched water ready to eat.
