Product review (1 stars): Don't waste your money, buy the original Samsung replacement
Purchased this filter to replace the one in my Samsung Model KF4287HARS French Door Refrigerator.  Installed as instructed and ran through about 6, 20 ounce cups of water to bleed out the air and any impurities from the filter.  Thought all was well but noticed later that day when the ice maker ran, system started making a knocking noise.  Assuming there must still be air in the line, ran through the 6 cup process again.  But this time, every time I ran the water it knocked for the first 5 seconds or so.  I also noticed the water was coming out with much less pressure.  Tasting it, there was a marked change in the quality we had enjoyed since purchasing the refrigerator.  After another day listening to the knocking, I became afraid I was damaging the refrigerator and put back in the old filter.  Knocking went away, flow returned to normal and taste improved.  Ordered the Samsung original and chalked this up as a lesson learned, you get what you pay for.
