Spent time looking for shop vac replacement cartridge filter exact model fit. Needed to clean messy drywall powder inside home after after hotwater pipe broke under garage foundation. Two filters arrived fast in plain pastic wrap, no model number, and did not fit as the seller advertised. The filter would not slide down the ball cage, and the screw on cartridge filter cap for my shop vac filter did not fit the cartridge filter. I feel like the seller falsely advertised the exact shop vac model fit and does not care for wasting my time and causing delays in cleaning up. I contacted Shop vac manufacture and went to a major home hardware store for proper fitting shop vac filters.
