Have a RIDGID wet dry vacuum filter on hand whenever the job calls for it with this 16-count, HEPA material pleated paper filter value pack -- buy more and save more. The filtration system captures allergens and traps particles such as everyday dirt, drywall dust, pollen, and pet dander. The replacement HEPA material filter 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 wet dry vacuum life as it protects the motor from harmful dust and debris. The HEPA Material filter fits all RIDGID wet dry shop vacs 5 gal. and larger and should only be used for dry pickup. 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 VF5000 Fine Dust Filter (sold separately), VF7000 Wet Filter (sold separately), and VF8000 HEPA Filter (sold separately), depending on the job application and type of cleanup mess. Also, a range of value pack sizes (2-count, 4-count and 8-count) are available to accommodate a variety of project needs.
