Product review (4 stars): Replaces my GE-MWF filter
I bought this Water Sentinel filter to replace my GE-MWF filter because it's less expensive.  Installation is like the OEM filter, very quick and easy.  At first, it leaked, but that's my fault for not tightening the connections.  It does what I want it to do, which is make my water taste fresh.

This filter comes with a sticker to remind me when to change it.  I find that a nice touch.  If the price stays right, I'll buy this again in the future.
