Product review (5 stars): This filter works perfectly in my Kitchen Aid
I own a Kitchen Aid Superba Model KSC525INWH00 refrigerator.  I used to get the replacement filter cartridges at Sears for $50+.  The last time I decided to just forget about filtering the water because at the price I could just as easily use a Brita Pitcher.  Then I saw these filters advertised on Amazon for a lot less.  A little bit of cross checking around the web convinced me that they were the same filter without the Sears labeling for a lot less money so I ordered one.

I just installed it and everything seems to be the same except for some of the labeling.  It said "Double filtration" on the Sears one, but I imagine they all are double filtration.  And if they aren't, the water tastes the same and for the lower cost I'm willing to go with this one.  I'll be getting my filters from Amazon from now on.
