This filter was for my old Craftsman 9 gallon vacuum. The new filter was larger in diameter than the current one, but I quickly made a wider cap out of a plastic cap. The vacuum now works great with increased airflow. It also came with two foam covers meant to cover the filter, but they were small even when stretched. But they got as far as the old filter. Also included was a small brush, presumably you could use it to clean the filter.
