I have a Filter Queen Canister Vacuum cleaner and I change the Filter Cones on a regular basis, but I understand that this unit has at least one, perhaps two additional Filters that need cleaning and/or changing. I have not been able to find and change those secondary filters.

One is on the top of the unit, under the handle.. Give the black round thing on the top a twist.. The other is under the motor. Grab the motor off the canister where the cone filters are . There is a black cone shape that makes up the bottom of the motor housing. There is a finger nut to unscrew that removes that cone. Filter is under there with a retaining ring that holds the filter on.

I can't believe no-one has answered this question in 3 years! I have the same question. I can tell you that there is another small filter in the very top, just under the handle. Twist the center piece and pull it out and turn it over and you will see the filter and can remove it by loosening the two little screws. I think there may be another one but I haven't had time to look just yet (in the lower cone apparatus). Will report more later.
