Product review (5 stars): Perfect fit, delicious water!
These filters were a perfect fit for my Fisher Pykel refrigerator.  I was skeptical at first since these were $40 less than the manufacture recommended filters.  Living in Salem, Oregon, we have excellent tap water already so we do not need to filter out any bad tastes in our water.  I will definitely be buying more of these and won't feel bad about having to replace the cartridge every six months.
