Product review (5 stars): Perfect substitution for GE MWF at about a 30% savings
Works perfectly as generic equivalent for GE MWF filters for a fraction of the cost. We are a family of 3 and this filter lasts us a solid 6 months.  Longevity using the OEM MWF lasted the same 6 months, so there is no performance or longevity difference - - - just about a 30% savings.
