Product review (5 stars): As advertised and fair price.
Product arrived on time and as advertised.  This is the OEM version that has NSF/ANSI 42 and 53 certification.  Buyer beware cheaper 3rd party filters are only NSF/ANSI 42 certified.  42 is for Aesthetic Effects...IE taste. 53 is for Health Effects IE chemicals and other health related contaminants.
