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.

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!

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.

In my opinion, The Companys staff are very intelligent and understands the very atom of the product they offer. This is one of very few companies that I never feel like I’m being “sold”, rather, they educate. I like my Alkaline water a lot and the price was perfect.
