Product review (5 stars): This filter was a perfect drop in replacement for the OEM Samsung filter
This filter was a perfect drop in replacement for the OEM Samsung filter, at a much lower price.  No leaks, and it's identical to the OEM.  The key feature to look for in a replacement filter is ensuring that it comes with two o-rings, like the Samsung.  This filter does have two o-rings, and is an exact dimensional match as far as I can tell.
