This is a non-powered hydrogen bottle from Viiva. It's a great product that makes hydrogen water in just one minute!! When you put in mineral water or purified water, you can see hydrogen bubbles forming inside within seconds. This single bottle can generate 300 liters of hydrogen water. Simply fill it with water and let it sit to create fresh hydrogen water. You can use it semi-permanently by replacing the cartridge. Weakly alkaline 1225ppm It does not have a water purification function. #viiva #hydrogenbottle #non-powered #antioxidant Thank you for viewing.
