Product review (5 stars): Worked fine, solid replacement for SmartWater MWF.
I have an older GE Profile Performance side-by-side fridge, model TFX25PP (analogs are the TFX26PP and TFX27PP). This filter worked fine as a direct replacement for my prior filter - a GE SmartWater MWF. I had to swap an adapter from my MWF to this unit (pops right out the old and into the new), but beyond that it was simple. The new filter screws in exactly where the old one left off, sits flush, fits tight, and is the right size.

Make sure you run the new filter a while to shake out any particulate matter and clear air from the lines.

Water from this filter tastes fine, and - as one great reviewer put it - I'm still alive to tell you about it.
