Product review (1 stars): DO NOT BUY
DO NOT BUY.  These are NOT a replacement for a GE GSWF filter.  Had to return them the same day due to low flow.  One way to tell they won't fit is GE has a blue fitting at the end of their OEM GSWF filters with a pinhole in it.  I believe this pinhole creates the necessary pressure for normal/high water flow. The WaterSentinel doesn't have this part, instead the water flow is unrestricted.  Discovered this after the fact when comparing filters.
