After having some issues getting the correct filter from Amazon (they kept mailing me Filter 3 instead of 4) I am happy to report that on my 3rd try I received the correct one!  The filter is easy to install in the fridge.  Ours is inside the fridge on the top right under a "door".  You just open the door and twist the filter out, then I put it in the fridge sink right away because water kept coming out.  They also say to filter 3-4 gallons of water through the filter before installing it.  I held it under the sink I am unsure if there is a better way.  Ordering it this way cost less than at a B&M store or their website.  I will be back for another filter in the future.
