I was tired of going to HEB and filling up a 5 gallon water jug every week. A friend recommended a reverse osmosis drinking water system that I could just park in my kitchen. I searched online and saw that Kinetico was close by to my house. I stopped by one day to see just how big these units are. Chris showed me one of their drinking systems called the K5. It's small and fits under my sink. I had it installed later that week. No more carrying around 5 gallon water jugs!
