The Fein HEPA Filter works with Fein I, II and III Turbo Vacs. Ideal when working with hazardous small particulate dust or if allergies/related health concerns are an issue. Installing this filter gives your Fein Vac a true HEPA rating when used in conjuction with a paper dust bag (recommended). Do not recommend using with a cloth filter bag. HEPA Filter mounts onto float valve cage located on the bottom of vacuum head.
NOTE: Installation requires Cartridge Filter Screw (#21953) and Cartridge Filter Flange (#28640), both sold separately.
