Product review (5 stars): Replacement filter gets the job done at a fair price
This replacement filter is much cheaper than the Kenmore-labeled OEM part. I found it just as easy to install.  It definitely filters the water; not only does the water taste better (I think the previous filter was quite old), but the ice from the freezer has also lost its funky odor.  This filter does exactly what I had hoped, and I plan on replacing it once very six months.
