Product review (1 stars): Contradicting and misleading claims.
This filter claims NSF/ANSI 42 while also claiming the following in the product description "MORE Pure Filter components are NSF/ANSI 42 certified. That means this filter meets or exceeds NSF standards which insure contaminants such as lead and mercury are removed, but healthy minerals such as fluoride remain. Tastes great by leaving potentially healthy, beneficial minerals while removing chlorine, other chemicals and contaminants."

However, per the NSF - 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.

This means that this filter does not remove lead, mercury, or any other contaminants as claimed. I don't plan to use filter since all it appears to do is improve the taste and not actually filter out any harmful contaminants as claimed. In addition, the package, nor filter itself do not have any NSF certifications, leading me to believe it's not NSF approved.
