Product review (5 stars): Easy to Replace
Unlike the one reviewer who was able to test the actual filtration I cannot attest to that.  I figure GE should know what they are doing and the product should filter what it's supposed well.  I do appreciate he's review though.  Just nothing I can do about it if it doesn't work.  The water and ice taste just fine to me.  We live in Florida where the water smells like rotten eggs.  I get that smell from the shower but not from the water and ice of the frige.  So hopefully the filter is donig its job.

It is easy to remove the old filter and install the new one.  Just turn and pull it off and put it on the spoke and turn to the right to tighten.  Takes less than 60 seconds.

Update: 3/11/13 - Looks like it must be replaced every 6 mo.  That's when the red filter light comes on on the fridge.  Pretty sure the reason is the heavy chemical and metal content of the water here in North East Florida.  It is easy to change.  Just be prepared to spend $35 twice a year.

Update: 3/21/14 - Price just keeps going up and pretty sure it's not worth it.  Finding half price what appear to be knockoffs.  Google it.
