Product review (1 stars): don't order this from Crucial vaccum!!!
I ordered this filter by looking up the replacement #. What they sent was 3x5 inch irregularly cut filter without the wire mesh thats supposed to keep the filter from sagging in the water.  DO NOT ORDER FROM CRUCIAL VACCUM. THIS WAS TOTALLY DISHONEST. They are allowing a return but no "oops" or apology or trying to make it right. Just allowing be the bother of a returns process. I wish there was a spot to post a photo. It's laughable.
