Product review (5 stars): Great savings from the filters at retail stores
Fits perfectly and filters the water as well as any filter I've ever used.  Make sure to follow the instructions about flushing the lines as there is quite a bit of charcoal filter residue that comes out initially.  The box says 6-8 minutes or 3-4 gallons.  Worth it to make sure you are drinking clear, filtered water.  Great purchase and will buy again.
