Product review (4 stars): It fit, didn't leak, works.
I spilt a small amount of water removing the old GE MWF filter but didn't spill any installing this Supco WF287; clean-up took one paper towel. I had previously filled the Supco with water to minimize "sputter" from air in the lines and it worked -- it doesn't fill all at once immediately; I turned the tap on perhaps a dozen times to run a small amount of water, allow the bubbles to work out, and run another small amount. As a result I didn't experience any sputter, either. Taste initially is not significantly different from the GE (and is better than tap). Recommended.
