20090147435PARTICLE TRAP - An apparatus and method for trapping particles in a housing is disclosed. A high voltage terminal/structure is situated within a housing. A conductive material, having a plurality of holes, such as a mesh, is disposed a distance away from an interior surface of the housing, such as the floor of the housing, forming a particle trap. The conductive mesh is biased so that the electrical field within the trap is either non-existent or pushing toward the floor, so as to retain particles within the trap. Additionally, a particle mover, such as a fan or mechanical vibration device, can be used to urge particles into the openings in the mesh. Furthermore, a conditioning phase may be used prior to operating the high voltage terminal, whereby a voltage is applied to the conductive mesh so as to attract particles toward the particle trap.06-11-2009
