This genuine Hoover WindTunnel HEPA Cartridge Exhaust Filter fits in a door on the side of the vacuum. It consists of fanfold filter media in a black plastic cartridge. The cartridge measures 10 15/16" x 3 3/8" x 1/2". This design provides a large filter media area for reduced resistance to air flow while producing a high level of filtration which meets the stringent HEPA specification for the air that passes through it.

There is no seal around the parameter of the frame nor in the vacuum cleaner body so some air and fine dust can easily bypass this filter. This filter is interchangeable with the WindTunnel Exhaust Filter in a Black Frame with Seal.   For similar products see our list of current Hoover Vacuum Supplies. Show Less
