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.

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.

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!

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.

,,,,paid 5 hundred dollars for Cosan… ,,,,paid 5 hundred dollars for Cosan USA in 2018...now can't get 4 filters package for replacement....it looks like we lost money...... what a terrible company!!! .... very regret that bought this Hydration system.... in 1.5 yrs we must throw it in garbage.
