Works very well for us .We have well… Works very well for us .We have well water with a good amount of sulfur,and it tastes great coming through the filter!

Affordable Affordable, had to pay to have it installed under sink leading to a separate faucet. Glad it is not sitting on my countertop. The filter that produces the H2 water seems to stop doing that before 3 months. This is disappointing, but I'm glad to have the H2 water some of the time.

The water is fantastic and the only… The water is fantastic and the only complaint in the office has been the speed of the water distribution and the water temperature(apparently most of my coworkers like cold water to drink)

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!

water pours way too slowly -
