you may get a few other names but Kent is a nice unit. You can not go wrong with one. Make sure that you get a ro with the di chamber also. The di is good at taking out phosphate. I actually added a 2nd one at the end to make sure the new water is as close to 0.0. You also need to get a water hardness pen or a inline meter, less than $50, to check if your di chamber needs to be changed you should get 2 to 5 hundred gallons from a di chamber.
