Hi Farida, Thank you for the review and the helpful information on portability. Blessings, Cosan/USA
I’m fortunate to live close to the company/warehouse and I always do a walk-in when I need something. In my opinion, The Companys staff are very intelligent and understands the very atom of the product they offer. This is one of very few companies that I never feel like I’m being “sold”, rather, they educate. I like my Alkaline water a lot and the price was perfect.

Hi Jason, Thank you for your kind words and noting our dedication to education. Cosan/USA serves as an educator within an industry that we understand through our own research and development of Cosan/USA product and the refinement of other great products produced by outstanding companies working toward the same common goal of delivering world class purification products. Blessings, Jim
Good quality product that doesn't require electricity or electrode replacement. Hydrogen lasts a lot longer than electrode-generated hydrogen water, all at a fraction of the price. I was using very expensive bottled hydrogen water to help clear my eczema, but stopped after I ran out with some symptoms returning. After using the Pure Hydration machine for 1.5 months, my neck is nearly clear again. Would recommend this machine to anyone wanting affordable, high quality hydrogen water.

Hi Albert, Thank you for your review and for sharing the benefits that you've experienced using Pure Hydration. Increased water intake coupled with antioxidants and high pH is just the thing you need when dealing with eczema related asking disorders. Blessings, Jim

Thank you Jim with all your help helping me and my friends enjoying our alkaline water. Makes us feel so happy and vibrant. Hydrating is keeping us healthy and strong and complimenting our workouts to get us fit and in shape. Thank you.

Hi Amy, Thank you for your review and a big shout out to all your friends. Keep up the good work in the gym and stay hydrated my friend. Blessings, Jim
Great product. We made it through the 1st 6 months w/out a glitch. I was impressed initially with how this company really tried to think of everything for the install. They gave me everything I needed to install and more. Water tastes great right through their recommended time frames to change filters. What's left to say. Thank you Cosan
