Product review (5 stars): EcoAqua EFF-6013A is a quality replacement for the MWF filter.
For those of you looking for a cost effective replacement for the GE MWF filter, it's the EcoAqua EFF-6013A. I've also purchased the Tier-1 filters, and they won't fit in my GE refrigerator. I've had no issues with the EcoAqua filter.
