Caused stomach pain/digestive issues. Three of us drank the water exclusively from the water system all throughout the day. We noticed after about a year that each of us had developed stomach issues. I suggested we stop drinking it for a week and stick to our filtered water out of the refrigerator. All of our issues resolved within a week.

Improved Quality of Life I have been using the alkaline water system for approximately one year. It has changed my life. I have sung the praises of this system every time I have had the opportunity. I have struggled many years with food allergies and sensitivities that affect my gut and skin. The improvement has been remarkable and drastic. The only water I ever drink at home is alkaline. I carry the bullet with alkaline water when I can. I highly recommend this product.

confused I don’t even know how this company got my email. And I get sent a survey for “choosing” them. I’ve never bought any products.

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.

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.
