Product review (2 stars): Returning: Filter only certified to NSF 42, not NSF 53 of OEM GE MWF filter
Bought this product based on the positive reviews and comments regarding this filter's equivalency to the OEM GE MWF filter.  However, I'm returning it after receiving it.  This item is certified to NSF 42 which refers to the taste of the water, not the more stringent NSF 53 standard for improved health effects.  There is no evidence that this filter removes the contaminants that the GE OEM MWF filter does remove.  Beware of a misleading review here that lists the contaminants supposedly removed by the filter - notice that the review is for a different filter, NOT the EcoAqua EFF-6013A.

There are comments that this filter supposedly passed internal certification for removing contaminants.  I don't see evidence justifying those statements.  Even if it was true, why wouldn't EcoAqua go for the NSF 53 standard and stop at the NSF 42 certification.
