The purpose of this work is to develop a new type of particle collection filter using electrical discharge technology. The new filter must be high efficiency and applicable to air conditioner to use for household, so we suggested the new type filter. The new type filter has a distinctive feature except characteristic of ESP, a thickness of collecting electrodes is thicker than that of existing type ESP. When particles come into the filter, the particles will collide with side surfaces of the collecting electrodes. At the same time of particle collision with side surface, the particles are charged by the collision and collected by electrical force. Therefore, we called this type "Ion Impactor". We optimized condition of thickness of collecting electrodes and applied voltage using six sigma method because thickness of collecting electrodes and applied voltage are very important to improve the collection efficiency. We analyzed distribution of electric field line, the electric field lines were uniformly distributed on the side surface of the collecting electrodes. From this analysis, we can see the improvement of the particle collection efficiency. We made the ion impactor type filter on a large scale to equip to the air conditioner, and measured the particle collection efficiency. For the 0.1∼0.2㎛ range particle, the collection efficiency was higher than that of existing type ESP by 30%. The collection efficiency of the 0.3∼0.4㎛ range particle was higher by 12%.
