Product review (5 stars): so far I am very happy with this purchase
This certainly appears to be an OEM Samsung filter made in Korea. I just changed my filter for the first time and the one that came with the refrigerator was labeled 'fresh water'.  It indicated that it filtered chlorine and particulate Class III, which is NSF/ANSI Standard 42, an aesthetic effect.  The box for my replacement filter was labeled 'fresh water', yet the filter itself was labeled 'mineral water', describing multiple things it filters, which is NSF/ANSI Standard 53, health effects and a much higher standard.

Without knowing more, it would appear the 'mineral water' filter does much more in the way of filtration, but the quality control in packaging is lacking here, as neither is provided or listed as a choice when purchasing and in my case, the box indicated one and the filter itself the other.

That said, so far I am very happy with this purchase.  It fits correctly, no leaks have developed and it appears to be working as it should.  I believe the 'fresh water' filters are intended for city water supplies and the 'mineral water' filters are intended for those who have a well-water supply.  If anybody has more information I would be happy to review it.  Regardless, accurate descriptions should be listed for these different options and appropriate choices should be listed.
