Product review (5 stars): Compatible with Kenmore 46-9990 Filter
I changed my original review, as I was having a great deal of difficulty installing this filter.  After further consideration, I put a small amount of Vaseline on the O-Rings and was able to install the filter.

My original review was not so good, so I am happy to be able to upgrade it, as I do not like giving bad reviews.

Water quality and taste is good, and unit does not leak.
