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.

RO unit to Pure Hydration ??? I bought my Pure Hydration System last October 2018. The connection set-up was from a Culligan RO system. I followed the installation procedure from the Cosan YouTube video. Bought a couple of reducers to connect to my existing RO unit. My whole family was drinking from this set-up since it was first installed until last Saturday(March 9); my wife asked me to check the PH value and found out to be only 7. Checked the water coming from the faucet and it’s higher than 7. Is the RO unit affecting the filters of the Pure Hydration? I’m confused. Need your help.

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!

Was not pleased with customer service or company standards. The main reason why I am giving a 1 star review is their customer service was pretty rude to me when I wanted to return my product. The rep I spoke with rejected the return and after a few emails, finally said the only way they would return it is if the box was never opened and they would have to take a $100 restocking fee. I also believe that the filter replacements are extremely expensive, not to mention the apparatus itself is about $500. Finally, my last complaint is that I was not able to use my warranty as the time for me to sign up elapsed since I was in the midst of trying to get an authorization to return my product. Overall, a bad customer experience to say the least. To be fair, the water filter does appear to be working well so it is a good product. It brings up the PH of my water 2 full points from 7 to 9, but my review is based more so on the company. I will not be recommending them to anyone or purchasing from this company moving forward.

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
