I made an appointment with the lifetime water system company, and the person showed up 30 mins early and left after 2 hours!We told
the person that we would think about buying the filter but he still was almost forcing us to buy it at that moment.
Also the person kept telling us to work for the company which was a little bothersome. Also as far as I am concerned the test might be rigged. Also the person wasn't professional at all.
I hope i can find a less expensive filter.For anyone else reading this, don't fall into the companies trap.
