Ultra-filtration vacuum system

An ultrafiltration vacuum cleaning system comprising;

• a first liquid stage filter comprising structure to direct particle laden air into a vortex in a circular cyclone chamber over a surface of a first liquid medium to direct particulates in the air to a wall of the cyclone chamber for collection by the first liquid filter medium and to create sufficient turbulence in the liquid medium to at least periodically wet the wall,
• an open-pore labyrinth filter for filtering air coming from the first liquid stage, which provides a convoluted path through which the air passes,
• a second liquid stage filter for filtering air coming from the labyrinth filter and comprising 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 into the second liquid filter medium, the dispersion chamber constructed with surfaces against which the second liquid filter medium is propelled by the energy of the injected air to disperse the medium in the air,
• surfaces upon which water droplets dispersed in air leaving the second liquid stage impact and become retained to remove essentially all of the liquid droplets in the air coming from the second liquid stage.
