The RIDGID HEPA material pleated paper filter is designed for your RIDGID wet dry vacuum (5 gal. and larger) to capture allergens and trap 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. This product offers one HEPA Material Filter that 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 the VF5000 Fine Dust Filter, the VF7000 Wet Filter, and the VF8000 HEPA Filter, depending on the job application and type of cleanup mess.
