Product review (1 stars): Whirlpool #4396701- Didn't fit, wasn't same size
Whirlpool:
Didn't fit right, couldn't install. The end of the filter that inserts into the sealing area is .005 larger than an original one hence it being a problem inserting it all the way in. It also has sharp edges (not slightly rounded like the factory ones) on same area that makes it hard to insert it all the way in. If you work enough it will eventually push in. After finally pushing it in I was unable to turn it to lock it in. When I pulled it out to see what might be the problem black water came out of it (see picture).

Also the part of the filter that you slide the handle over is too small and doesn't give you complete control when installing it (See picture). When I pulled the new one out the handle came off and had a hard time pulling the new filter out without it.

I hope I can return it without it costing me shipping.
