Replacement Cartridge Filter Compatible with Shop-Vac 90304 90350 90333 Fits Most Wet/Dry Vacuum Cleaners 5 Gallon and Above, Compare to Part # 90304 (2)

Filters work great but don't forget to keep the plastic disc from your old filter that holds the filter in. They don't come with these. If your replacing the type of filter that has the bottom built in you'll need to buy the holder for these separately. Used one of these when sucking up water. Worked good and was able to dry it and keep using it as a dry material filter again.
