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.

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.

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.

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.
