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.

Important change My water now has a good taste & I would recommend this company to anyone who wants Alkaline water. I am reading a book called the PH diet & it says if you can only change one thing right now It would be to drink Alkaline water since it is so important for you.

This machine does a good job on the… This machine does a good job on the extremely hard water in my area. I can’t fairly rate since the taste isn’t ideal, it’s tolerable when chilled. Cosan is simple to install, takes very little space very user friendly. For the price I would reccomend if your tap water isn’t too hard.

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!

Love the water Love the water. Set up is easy. We have very little counter space, so we had to set below the sink. This means a different set up, and the water does not immediately turn off. It takes about 15 seconds as it dribbles to a stop.
