Product review (3 stars): I have used the BEST filter brands as well
I want to be clear about this. This is my 3rd GE filter, 1st from Amazon)  However, I have used the BEST filter brands as well. They all worked great but I went back to the more expensive GE because I read somewhere that most of the brands did the job of filtering out everything except one particle/element/chemical and only the GE brand filtered everything. However, this was the first filter that had very slow water flow. I had not noticed water flow this slow with any of the filters before including the best brand - hence the 3 stars. I replaced the GE and now the flow is just fine. The "bad" GE filter may have been just a bad one from the factory because it did not look like anyone tampered with it. The plastic seal/wrap was the same as the others. Hope this helps.
