Product review (3 stars): Changed the design - don't fit anymore!
New WFC2201 filters are either mislabeled or they changed the design but they don't fit! I've been ordering this filter for a few years and the latest they sent has a new neck seal mount. Different than previous WFC2201 filters (look at the label). Since there's no return on these, i'd strongly suggest not buying until this is resolved. Hopefully this was the case of sticking the wrong label on the wrong filter and was a one off. I doubt they would change an existing design
