Product review (5 stars): An ANSI 53 certified filter.
Perfect OEM replacement for the factory filter in my Samsung RF28HMEDBSR refrigerator, with a HAF-CIN/EXP cartridge and recommended replacement with DA29-00020B-1.

This filter costs more than others, almost double, because it does more than others, much more than double.  It is a certified ANSI 53 filter which includes ANSI 42.

ANSI 42: Establishes the minimum requirements designed to reduce aesthetic or non-health-related contaminants, such as chlorine, taste, odor and particulates.  Products are certified only for material safety, pressure bearing and structural integrity, not for filtration capabilities.

ANSI 53:  Establishes the minimum requirements for the certification of filtration systems designed to reduce specific health-related contaminants, such as Cryptosporidium, lead, volatile organic chemicals(VOC) and asbestos that may be present in public or private drinking water.  The reduction claims are verified by this standard.

Basically, ANSI 42 may make your water taste better, but ANSI 53 is required to make your water safer to drink.  What is the purpose of filtration if it does not make the water safer to drink?
