"Upgrade your shop vacuum with the Stanley 08-2566H HEPA Cartridge Filter for cleaner air and longer-lasting performance. This high-efficiency filter captures up to 99% of fine dust and debris, including particles as small as 0.3 microns—perfect for heavy-duty cleanup in workshops, garages, and construction sites. Its 360° pleated media design provides maximum filtration surface area, while the reinforced steel mesh cage prevents collapse under high suction, even during liquid pickup. This filter is compatible with a wide range of Stanley vacuums and most other 5–18 gallon wet/dry vac models, including select DeWalt, Craftsman, and Ecomax units. Reusable and washable, it’s an eco-friendly alternative to disposable filters—simply rinse, dry, and reinstall."
