Product review (5 stars): Water Filter -- Best way to get the replacement
I had been getting the replacement filters at the appliance store every time the "warning" light went on.
The Amazon price was better, delivery was quick, and I ordered the 2-pack.  It's the only way I'll ever buy these!!

Update:  Since installing there has been a major leak.  Apparently this is a current issue with Samsung.  This is a different filter than the earlier ones -- I thought it was meant to be improvement.  Wrong!!
