Review on IOYIJOI 1 Pack Wet/Dry Filter Replacement: Craftsman Vac 9-17816 (5 Gallon & Larger Vacuum Cleaner) by Samantha Hervey

I have a 6 gallon Craftsman Shop-Vac with model prefix 113 and it doesn't fit me. The part that fits on top of the cap is too small to fit through the hub. None of these filters seem to list dimensions other than overall height and overall width, so it's impossible to buy them online and be sure. The hole in the filter should be 5 inches and only 4 and 1/4 inches. Absolutely useless.
