Product review (5 stars): Replacement filters
I recently replaced my water filter, for the first time, in my new Samsung refrigerator.  Thanks to the pink warning light I had time to order on line and have replacements ready so that I didn't have to pay full price in a local store for a Samsung replacement.  This filter installed easily and is working great!  My only tip/advice is that you really do have to run the approx. 3 gallons of water through the line (Samsung's instructions) to get out all the air.  Until you do this it will continue to drip.  Since I live in the desert, I had my bucket ready and used all that water on my outdoor plants.
