Abstract
In various aspects of the invention, electrostatic filters having insulated electrodes are described. In such embodiments, care is taken to prevent the accumulation of opposing charges on the insulation, which, over time, would serve to significantly degrade the strength of the electrostatic field created in the dielectric, and thus reduce the performance of the electrostatic filter. A variety of mechanisms are described for mitigating the opposing charge buildup problem.
