Product review (4 stars): Inexpensive replacement for GE Smartwater MWF filter -- no charcoal leaks
Bought as a replacement for the more expensive GE Smartwater MWF refrigerator filters and they fit like a glove and performed flawlessly. Our water from the tap is good, but this does take some of the chlorine smell and taste out of the water.

While the water tasted the same from the refrigerator with this filter and the stock one (to me and to my wife), I did notice the stock filter leaked much more charcoal after installation. The initial water coming out of this filter was clear from the beginning, though I did drain off two gallons as recommended.

I'm not sure what this tells me. It could mean a number of things, some good, some bad. Anyway, I just installed my second one in the two pack three days ago and for the price, I will be buying more rather than the higher priced OEM filters, but for now I am withholding a star until I am sure the filter materials are as good as the originals are. As a plus, these filters come with date stickers so you'll know when you installed them and when you need to replace them, though I run mine until the refrigerator light comes on and the flow slows.
