Product review (3 stars): Buyer Beware
Buyer Beware

I bought these filters because they claim to be a 1 for 1 replacement for the Samsung DA29-00003G Aqua Pure Plus water filter. They are NOT. Don't misunderstand, they physically fit and produce good flavored water, however they do not filter everything the Samsung filter is capable of filtering. These filters only satisfy NSF/ANSI 42 treatment standards, which are for "aesthetic effects". They do not meet NSF/ANSI 53 treatment standards which are for "health effects". I've included the descriptions directly from the NSF website on filtration standards:

NSF/ANSI 42: Drinking Water Treatment Units - Aesthetic Effects
NSF/ANSI 42 establishes the minimum requirements for the certification of POU/POE filtration systems designed to reduce specific aesthetic or non-health-related contaminants (chlorine, taste, odor and particulates) that may be present in public or private drinking water.

The scope of NSF/ANSI 42 includes material safety, structural integrity and aesthetic, non-health-related contaminant reduction performance claims. The most common technology addressed by this standard is carbon filtration.

NSF/ANSI 53: Drinking Water Treatment Units - Health Effects
NSF/ANSI 53 establishes the minimum requirements for the certification of POU/POE filtration systems designed to 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.

The scope of NSF/ANSI 53 includes material safety, structural integrity and health-related contaminant reduction performance claims. The most common technology addressed by this standard is carbon filtration.

Having said the above, these aren't bad filters. They do a good job of enhancing the taste of my refrigerated water, hence the 3 rating. I'm on a good public water system so that is probably actually sufficient for my (and probably your) needs and they are significantly cheaper than the Samsung filters. Recognize that you get what you pay for though. If you are worried about lead, cryptosporidium, giardia, MTBE, etc, then move along, there's nothing to see here...
