Abstract: A cyclonic separation system filter cartridge with a cylindrical body formed into at least thirty pleats having a solid bottom surface, an open top surface, a rigid inner cylindrical core, a top cap member substantially covering the open top surface except for a central circular opening, and a handle attached to either the rigid inner cylindrical core or to the top cap member, extending across the central circular opening. The pleats form a plurality of filtering chambers. Also, a mounting apparatus is disclosed that includes a top mounting flange, a retainer plate, removably connectable to the top mounting flange, a bottom plate and tie bracing connected to the mounting flange and the bottom plate, wherein the mounting apparatus is configured to be mounted, via the top mounting flange, within a cyclonic separation chamber, wherein the tie bracing is configured to extend along an internal wall of the separation chamber.
