Product review (1 stars): don't buy generic
I bought to replace the original filter that came with Samsung fridge.  I replaced the filter, ran 2 or 3 gallons water through and everything seemed fine - water came out of dispenser and no leaks anywhere.  A few days later I realized there was no ice.  I reset ice maker and got a few cubes then it stopped again.  Called Samsung and thankfully fridge was still under warranty.  They had me do a few tests over the phone (does 8oz of water come out in under 10 seconds? - yes) before deciding to send repairman out.  He told me there wasn't enough water getting to the ice maker because of the generic filter.  He took the filter out and it worked fine. Lesson learned!  Don't buy generic.  Plus, nowhere on the filter or the box it came in did it say anything about NSF rating.  The filter probably did nothing at all.
