Product review (5 stars): Don't Believe the G.E. shills
My G.E. refrigerator was manufactured in 2010. This filter replaced a factory MWF and works flawlessly. If I was producing competing water filters, I wouldn't pay G.E. for "certification" either. Save yourself 20 Dollars and buy this filter.

on a side note...2 of my G.E. appliances have needed repair in just 32 months of operation. new thermistors in the freezer and a sagging apron on the washer. The appliances were provided by the builder. I will never buy anything new from G.E. again. Just parts for their faulty products until their service life is over.

I hope Water Sentinel NEVER pays G.E. to "Certify" against certain microbials. Microbials which will not be in a public water system anyway. The filters have the same components. If Water Sentinel were to seek certification, filters would cost as much as the G.E. one.

I am so happy to find filters that won't be paying a kickback to G.E.
