Abstract: An ultra-filtration vacuum system with a first liquid stage filter and that has structure to direct particle laden air into a vortex in a circular cyclone chamber over a surface of a first liquid filter medium to direct particulates in the air to a wall of the cyclone chamber for collection by the first liquid filter medium. An open-pore labyrinth filter is provided for further filtering air from the first liquid stage. A second liquid stage is provided to filter for filtering air from the labyrinth filter and has a dispersion chamber with an inlet that directs the particle laden air from the labyrinth filter directly into a second liquid filter medium to transfer momentum of the air directly to the second liquid filter medium, the dispersion chamber constructed with surfaces against which medium is propelled by the energy of the injected air to disperse the medium in the air, the dispersion chamber shaped such that a cascading and undulating liquid surface is formed.
