Product review (5 stars): Saved Money and Worked with No Problems
The WSS-1 filter was an easy plug in replacement for the factory filter on my 28 cu ft Samsung French Door Refrigerator.  I recommend buying the 2 pack as it offered the lowest per filter price, even lower than the 3 pack.  No drips at all.  I just placed a little of the included silicone lubricant on the o-rings and put it in.  Very easy.  Ran a gallon of water to remove the little bit of charcoal dust from the filter and everything is good.  Water and ice are fresh tasting, clear, and everyone in the family was happy.

Why spend more?
