Product review (5 stars): Good replacement for the GE GWF Cartridge
I purchased this MWF filter to replace a GWF filter and was relieved to see that it was a compatible replacement. I just could not find a GWF replacement filter anywhere. My refrigerator requires an adapter for this type filter (it originally shipped with a Culligan filter), and the old adapter that was on the GWF filter fit perfectly onto the MWF.

It took less than a minute to install.
