Product review (1 stars): NSF/ANSI 42 is certification for aesthetics -- taste and smell ...
NSF/ANSI 42 is certification for aesthetics -- taste and smell only (chlorine and sediment).  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, lead, volatile organic chemicals (VOCs) and asbestos that may be present in public or private drinking water.

The Amazon page claims that this filter is NSF/ANSI 53 compliant, but the specification sheet states that it is NSF/ANSI 42 compliant only.

If you want to protect your health, DO NOT buy this filter.
