ABSTRACT:
An apparatus and method for minimizing contamination buildup on corona emitters that are employed in an ionizer. Contamination buildup control is accomplished with solely electronic means. High voltage is applied to the emitters with waveforms that serve to push contaminants away from the emitter, rather than attracting contaminants toward the emitters. The results are fewer cleaning cycles, more time between cleaning cycles, and more stable ionizer operation.
