Product review (1 stars): Be Careful!!! Water leak!
Bought this filter, installed it and woke up this morning with water all over the kitchen, dining and living room floor, leaking through the floor to the garage.  What the heck!  this is crazy.  What a mess. So today I started reading the reviews only to read some of the same. Apparently there is a connection issue.  My model is a 2012 RF4287HARS.  So Samsung no longer sells the original replacement filter.  Now what?  Buy a knockoff and wait for a water leak to ruin your wood floors?  We've had our Samsung for 3 years and was forced to use these knockoffs the last two times.  The first time the O-ring came off and got stuck in the fridge.  This time, it took two days to get the old filter removed, short of using dynamite to blast it out of there.  What a piece of junk. I will be returning this for sure.
