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.

Improved Quality of Life I have been using the alkaline water system for approximately one year. It has changed my life. I have sung the praises of this system every time I have had the opportunity. I have struggled many years with food allergies and sensitivities that affect my gut and skin. The improvement has been remarkable and drastic. The only water I ever drink at home is alkaline. I carry the bullet with alkaline water when I can. I highly recommend this product.

Great products, awesome customer service, works as advertised! Great products, awesome customer service! I have highly recommended CosanUSA's Pure Hydration and filtered bottle water container to my family and friends. The Pure Hydration is very easy to set up and works exactly as advertised. The water container is perfect to have when on-the-go. I even filter bottled water from the store just to have my drinking water at it's purest ph levels. (Most bottled waters I've tested were very low in ph levels) Customer service is easy to get in touch with and inquires were always professionally handled. These products are absolutely a great investment in keeping your body healthy! Check out their youtube comparison video: CosanComparison1

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.
