Product review (5 stars): This fixed my problem with water filters only lasting a short time resulting in slow dispensing.
I have a new 4 month old Whirlpool side by side refrigerator and the Everydrop filter that came with the frig only lasted 2 months instead of 6 months as advertised. So I replaced it and it only lasted 10 days and then dispenser slowed to barely above a drip.  I called warranty service and they ordered a new filter housing and sent a guy out to install it.  I was unable to close the door on the filter housing after inserting the filter but the repair guy said 'just get a guy to do it for you'.  Three hours after he left the door popped open and I could not close it.  I took a big piece of duct tape and taped the filter door about 90% closed and it worked!!  Water dispensed properly with no leaks.

I then ordered this Whirlpool housing and this morning I installed it.  It works beautifully, the little door closes easily and no leaks.  The problem as I see it is the original housing and the one Whirlpool sent had a filter housing door that was too wide.  The door was overlapping the cover that goes over the housing.  Since the cover on this one is narrower, it sits inside the housing cover and closes easily.

I called Whirlpool to let them know. They said this part goes with the 25 cu foot frig whereas mine is 21.  I don't really care because it works and they are sending me a gift card to cover the cost of this housing.  Installation would have been easier if I had the proper screwdriver for the two bolts that hold the housing to the wall and the cover.  I used an adjustable wrench but really needed a nut driver I think.
