The best alkaline water system! The best alkaline water system!! I love mine and it is so easy to use and take care of! My skin was suffering from acne and after religiously drinking from the pure hydration water system my skin has definitely cleared up! I notice a huge difference in my mood and digestive system when I don’t drink alkaline water now. I definitely recommend this company and their products. If you haven’t bought their shower head you are for sure missing out on healthy skin and hair!! Five stars all around!!

Affordable Affordable, had to pay to have it installed under sink leading to a separate faucet. Glad it is not sitting on my countertop. The filter that produces the H2 water seems to stop doing that before 3 months. This is disappointing, but I'm glad to have the H2 water some of the time.

Excellent after the sale customer service I purchased Cosan water filtration system Jan 2017. I use it everyday and love it. In April 2018 I received a 15% off coupon reminding me to purchase and change my now year old filters. I missed the deadline! to use the coupon. Bummer. But, how proactive of Cosan to remind then entice me to purchase filters (supposed to be changed every 6 mos or so)! I wrote an email thanking them and hoping to know when another great coupon would come out. I received an email promptly offering me 10% off as I recently retired and let them know any savings would help. They worked with me while also being nice. I love the response time and actions!

How do you not have the filters for an alkaline machine a few years old I bought my alkaline machine a few years and the filters Cosan USA sent me to replace are not compatible. How do you not offer the same filters for an older machine? I called and no one answers the phone. I sent an email through the website; and via my gmail. I read their return policy and I would be responsible to return the items. Where do I return it to? I am very disappointed.

water pours way too slowly -
