Our Hydrogen Rich Water Generating Machines are made from the highest quality and top of the line technology available. There are cheaper made Hydrogen Generating Machines on the market that produce toxic byproducts. We only carry Hydrogen Water Generators that are safe and implement the use of Platinum coated Titanium electrolysis plates. These plates do cost more then the cheaper stainless steel ones. But it is important to use these so toxic metals like molybdenum, chromium, and nickel are not leeched into the water.
