Product review (2 stars): ANSI / NSF certification claim is false.
Very deceptive claims regarding NSF certifications.  In small print on the box it says, "The testing of this carbon filter for compliance of ANSI/NSF standards conforms to the material and structural integrity requirements only."  In English, this means the product doesn't meet the standard for removal of contaminants or other impurities in the water.  The real GE filter is certified by independent testing to meet the full standards, and that's why it costs $50.  This, like all the others sold here, are cheap imitations and "fake" products that do nothing other than pass the water through a cheap activated carbon filter in a look-alike housing.  Rip Off!
