HFactor is hydrogen infused water. HFactor exists because decades of research have evidenced the ability of hydrogen infused water to enhance how our bodies feel, function and renew. And while other hydrogen infused waters use techniques that leave behind impurities or other additives such as Magnesium, our Reverse Osmosis filtering system ensures the purity and taste of our water, allowing us to deliver pure hydrogen and pure water, and NOTHING ELSE – so you won’t have to sacrifice clean taste for the benefits of hydrogen.
