Have a Shop-Vac that's not sucking in as much debris as it used to, or without the strength you remember it once did? If your Shop-Vac seems to be slacking on the job, the solution to your problem is as simple as replacing its clogged and congested cartridge filter. While cartridge-type filters like these can be shaken clean and reused, they too will eventually accumulate small debris that cling tight, cake-on and reduce your Shop-Vac's overall performance. These Shop-Vac Cartridge Filters are designed for use with Craftsman and Ridgid Shop-Vacs that feature large filter cages. They are NOT a product of, nor are they sponsored or endorsed by RIDGID, Inc. These Genuine Cartridge Filters are a product manufactured by Shop-Vac Corporation, and the material that they are constructed of helps to maintain suction power during both wet and dry pick up. Hurry and order yours today to ensure you have the correct cartridge filter, before needing one the day of tomorrow.
