What I got was exactly what they advertised but I was hoping the filters would fit as OEM filters. However, the filters arrived 3 days early. Sellers made no statements other than that "some modifications may be required". FYI, my modification was to use a piece of blue foam to create a "donut" that filled the space between the vacuum cap and the top of the filter. So that the wing nut on the vacuum cleaner can hold the filter in place, I sewed a steel washer. It's unattractive but functional. My shop vacuum is a 16 gallon vintage Sears.
