Product review (1 stars): This filter is NOT a substitute for UKF8001
I have a French door Maytag refrigerator, with the freezer on the bottom.  This filter is missing something, probably a seal or two.  It caused water to run down the back of my refrigerator, between the inner shell and the outer casing.  The water all went into the freezer through the air vents, and froze in the bottom of the freezer.  This caused the drawer to not close properly.  I didn't figure out exactly what was going on until all of the vents in the freezer were frozen over, and the temperature started to go up.  I am surprised that the water it dumped in the back of my refrigerator didn't cause it to short out.

This filter is not the same as UKF8001.  It is cheaply made, and does not work.  I almost lost a freezer full of food because of the shoddy design of this product.
