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.

I almost bought the $4000 machine I almost bought the $4000 machine, the competitor, then my son in law did research on line and told me about Cosanusa. I returned other One, all I need is water with high ph and don’t need other bells and whistles. Beforehand, I was spending way to much money at these specialty stores and it was a hassle running back and forth, straining my arm and fingers holding the heavy bottles. Now I just change cartridges. I was teking alkaline water for months then went off and felt lousy within two weeks before I realized I needed some kind of permanent machine . Bottles water is not good fir landfills it your body! I use stainless steel containers from Cosanusa. 👍 Martie Garcia RN

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.

The water is fantastic and the only… The water is fantastic and the only complaint in the office has been the speed of the water distribution and the water temperature(apparently most of my coworkers like cold water to drink)

Works very well for us .We have well… Works very well for us .We have well water with a good amount of sulfur,and it tastes great coming through the filter!
