Product review (1 stars): These knock-off filters get terrible reviews due to bad taste
FAKE-Made in China.  I paid the extra money for a real General Electric MWF filter.  I received a Made in China R-9991 Fits in place of MWF filter.  These knock-off filters get terrible reviews due to bad taste. I am returning it and not even going to test the water taste.  If I use it, I am stuck with it.
