Product review (5 stars): GE bypass filter for MSWF type
It seems to be genuine OEM part in GE bag (purchased via Amazon third-party "PANDORA'S OEM APPLIANCE PARTS").  I have an RO system connected to the fridge, so didn't need the fridge's extra filter.  This filter bypass fit perfectly for my GE Monogram PSC25NSWA fridge to replace MSWF filter, and there's been no issue with water flow.
