I don't know where to start after all the back and forth comments... I'll take a picture of the two systems. We went with two different systems because from what I read, kinetico is more advanced in their drinking water filters. They also use a larger diameter tubing which allows more flow. The culligan system is being used for the rest of our water. We were having issues with high levels of iron causing staining in and on our appliances and tubs and sinks. It was cheaper to go through culligan because of a promo going on and they guaranteed the issue would be resolved or money back.
