Product review (4 stars): Not an EXACT replacement, but good for my case
Please keep in mind this is NOT a 1-for-1 replacement of the OEM filter, but for people like me who already have whole house filters before the water ever hits the refrigerator, then this hits the spot.  Physical fit was perfect for me, it just does not filter to the same level as the OEM filters.  As an added benefit from the filter being a a bit more porous, my water comes out a LOT faster now. :)
