Product review (3 stars): I can't believe people pay so much for this.
I give it an "It's ok" rating because it's obviously better than nothing, but the salesman lied when he said it will make our Vegas water tastes better. It did NOT help in the least bit. The fancy water/ice in-the-door dispenser was useless for years until I finally bought an RO system after the prices came down on them. (I had been lugging home cases of bottled water from the store all these years.) For the price of 4 of these GE filters you can buy an under the counter RO that makes even our nasty Vegas water drinkable, plus it will do a much better job of filtering. No single carbon filter like this by itself can match the purity of RO filtered water regardless of brand. And it only took a few hours to install and I was taking my time. First thing I did after it was up and running was to throw this filter into the trash and install the bypass plug. Now I have 2 outlets with pure water. One on the sink and the other in my fridge door. Some people even buy ROs just for their fridge.

As for the argument that ROs waste water, the bottled water I used to buy was purified by commercial ROs in California of all places. So now I save money by not paying for someone elses RO water. Much cheaper than bottled water.

And on a side note Vegas recycles our waste water from the sewage system. If you drain your pool you have to pipe it down through your sewer line and not to the street drain, so they can recover it. So not much is really wasted.
