Product review (4 stars): Good as an aid but not a total solution
This filter came with my GE refrigerator which I've had for several years. At first I was very pleased in the improvement to water taste. But over the years the replacement filters seemed to be progressively less affective.

Then I used a Brita pitcher with water filtered through the GE and again the taste improved.

But then, without going through the whole story, I installed a whole house filter using a Watts housing and I have almost store bought water quality in the Brita. But it dawned on me I was providing 3 stages of filtration so improvement should be expected.

My main problems with unfiltered tap water are foul taste, chlorine, sand, and occasional sea related material. Was shocked to see sea shells, snails, and sand in my toilet tank. So it's no wonder the water had a foul taste. Often makes me gag. Plus I learned with my whole house filter (under $10 for a 2-pak of filters btw) there was all kinds of junk running through the lines because the Watts housing is clear and there was viable debris literally within 2 minutes.

So in summery if you ONLY had around $40 to spend on filtration I'd opt for a whole house filter. It has helped the best. But I would still buy this GE filter occasionally as an extra effort but feel good now because I know I don't have to depend solely on it. OTOH if you can't get a whole house filter installed and you're mechanically challenged this GE filter is better than nothing at all. Literally installs in less than 1 minute plus about 2 minutes to flush out the new filter.
