Product review (1 stars): Not what I expected
On the plus side, shipping was free and quick.

But when the filters arrived, they were loose inside a plastic shipping bag.  None of them were in boxes, and some of them were kind of smashed.  Although they are the same shape as the filters they are compared to (WF813), they do not seem as well constructed.  They are flimsier and lack the dark metallic-looking strip in the middle.

I will not buy these again, and I am trying to figure out what to do with the ones I have.  We went to Walmart and picked up several boxes of the WF813 filters to use instead.
