Review on Washable and Reusable Wet/Dry Cartridge Filter Replacement for Craftsman 9-17816 - Fits Shop Vacuum Cleaners 5 Gallon and Larger (White) by Brad Laverentz

This was listed as an exact match. Had not! The end through the inlet cage was not big enough or flexible enough to fit over the plastic case. I had to cut the inside edge of the filter housing. On the other hand, the male-threaded center rod hole had burrs on the inside that prevented the filter from sinking onto the vacuum motor housing, and the outside also had a burr that prevented the bolt on the locknut from being screwed down. on the pole. I drilled a hole to remove both internal and external protrusions. Now it fits and I'm sure it's a good filter, just not made for this vacuum as advertised.
