Product review (4 stars): NSF 42 & 53 filter, not check generic lables
Expensive, but make sure when comparing generic the NSF rating.  NSF 42 is really only for taste, ie chlorine and particulates.  NSF 53 includes cryptosporidium, giardia, lead, etc.  Would assume that is finer filter media size I assume.  This genuine filter is NSF 42 and 53.  Whole apples to apples thing. (ps: I have nothing to due with Samsung or filter companies, just trying to be helpful)
