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!

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.

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.

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.

This Pure Hydration system works great This Pure Hydration system works great. I've been drinking it for about 2 weeks now, and I feel much more energetic since i've been on it. Usually, by the afternoon I would feel very tired and sluggish, but ever since I started drinking this ionized hydrogen infused water, the afternoon's are not a problem, and I get a lot of work done now.
