Improved Water Quality: Hydrogen water bottle utilize advanced SPE and PEM electrolysis technology to rapidly generate up to 1600ppb of hydrogen ions in just 3 minutes. Using proton membrane separation technology to improve water quality, it has the characteristics of high hydrogen concentration and good stability. Food Grade Material: The cup body is made of high borosilicate glass, and the material is carefully selected to meet the ergonomic curved design. The hydrogen water bottle generator measures 2.9*2.9*9 inches and can hold 420 ml of liquid (about 14 ounces). It is portable and can easily meet your daily drinking water when exercising, going out, and working. Multi-function: The 2-in-1 design of the hydrogen water bottle, can directly drink hydrogen water or absorb hydrogen. The bottle is equipped with the extra nasal tubes that can be inserted into the lid interface if you prefer to directly inhale hydrogen gas. Use USB rechargeable jack, hidden design, sealing more waterproof; Easy to Use & Clean: Just press the power button, when the ionic water bottle starts, it will produce a large number of fine bubbles, the light at the bottom of the cup will constantly change; A healthy cup of hydrogen water can effectively reduce oxidation reactions.
