Tackle any mess and extend the life of your RIDGID 3 to 4.5 gal. wet dry vacuum with the included general debris pleated paper filter and wet application foam filter. The RIDGID general debris pleated paper filter is designed to capture everyday dirt and debris such as sawdust, dirt and typical debris found in a basement, garage or vehicle. The RIDGID wet application filter should be used when picking up high volume liquids with waterborne debris. Both replacement wet dry vac filters can be washed and, if dried properly, reused. Changing shop vac filters often is strongly recommended to increase the vac's performance and to help extend vacuum life as it protects the motor from harmful dust and debris. This filter offering provides a solution for both wet and dry pickups and fits most RIDGID wet dry shop vacs 3 gal. to 4.5 gal. With its patented Qwik Lock feature, the filter simply snaps on or off the shop vacuum for easy cleaning and to quickly switch filter options. RIDGID provides other filtration offerings, including VF3500 Fine Dust Filter (sold separately), VF3600 HEPA Material Filter (sold separately), and VF3800 HEPA Filter (sold separately), depending on the job application and type of cleanup mess.
