Product review (5 stars): Perfect replacement
I'm writing this review since there have been no others for consumers to view. This purchase was to replace a Kenmore 9915 water filter. It is the same as the Whirlpool 4396701. The filter cartridge is identical in size as the 4396701 we removed from the fridge with the exception of the base piece that the installation knob fits onto. It is slightly smaller but installation was no problem whatsoever. It fit perfectly into the slot with only the few normal drops of water. After running a few gallons of water through the water dispenser the water looks and tastes fine. We expect no problems from this unit and appreciate paying $18 versus $40 from Sears.
