I spent a lot of time researching this as an alternative to the Samsung filter.  This filter and no other replacement filter I could find were rated NSF 53 which  reduce specific health-related contaminants, such as Cryptosporidium, Giardia, lead, volatile organic chemicals (VOCs) and MTBE (methyl tertiary-butyl ether), that may be present in public or private drinking water.  I think this is a very important element and not worth the discount.
