Product review (1 stars): BEWARE! Apparently by Samsung/Amazon and they're fakes!
BEWARE! I'd read about fake filters being sold on Amazon, so rather than going for a cheaper option I selected the full price filter thinking it would be the real deal.  It came in a real looking box everything looked great until I noticed the label was printed a little askew, strange but I would imagine sometimes the labels go through the printer a little off sometimes.  But I also noticed on the filter I removed from the fridge (the one that came with the fridge from new) had a code number printed on it.  Dot matrix style, looked like it was a batch code or something.. real. The one I just received did not have this. Suspicions aroused i did some more digging online, also talked to a Samsung engineer to verify these are fakes.  It's fate was sealed when I read in the small print on the original label details on the data sheet for NSF certification.  Looking at the fake they've kindly admitted NOT CERTIFIED NSF (despite having NSF all over it).  It's a fake, if you just paid $48 for one of these please take note.  Photos attached
