This is perfect for my shark. I'm a little worried about the quality of the foam and fabric insert. The paper HEPA filter is fine, looks like the original filter that I removed. But the foam seems thicker and cheaper quality than the original Shark version, not sure if it will wear off or last as long. And the fabric you put underneath also appears to be paper and the one that comes with the vacuum cleaner is a fabric that can be washed. I don't think any of them last anywhere near that long. It's probably worth what I paid, but I wonder if I should have spent a little more for better quality.
