About this item UpgradeTechnology:hydrogen water bottle uses SPE and PEM technology to rapidly electrolyze water to separate and release H2 and O2, with high hydrogen concentration and good stability. Hydrogen Water Bottle, Water Ionizer Machine,Hydrogen Water,Hydrogen Water Generator.Hot or cold water can be applied, no limit to water quality.Suitable for all kinds of water , except pure water. Suitable for use at home, office and other places. 3 minutes mode：The generator has a 3 minutes mode, which means you can get high-quality hydrogen water in just 3 minutes, change the water quality,the higher the mineral content in the water, the stronger the electrolysis effect and the higher the hydrogen content.saving you time and effort.(Do not use water exceeding 60 degrees. The produced high hydrogen water is too hot. During the cooling process, the hydrogen will run away due to long time.) Easy to Use :The generator is portable and easy to use, making it convenient for you to carry it around and use it wherever you go. Portable rechargeable:hydrogen-rich water bottle made of high borosilicate glass, rechargeable via USB, water electrolysis can produce high concentration of hydrogen gas up to 1500 ppb.(capacity of 450ML) 1.5L of water per day is equivalent to the antioxidant value of hundreds of fruits and vegetables. Hydrogen-rich water can reduce toxic self-free radicals, thereby reducing human aging and enhancing immunity. increases energy levels and slows down the process of aging.
