Abstract
An air filter and particle removal system for eliminating impurities from air. The system is constructed with an upper electrode plate facing a lower electrode plate. A flypaper-like material is placed close to the lower plate with the sticky side of the material facing the upper plate. The plates have different voltage polarities so that when air is passed through the duct, charged particles within the air will move toward the lower plate and are caught by the flypaper-like material. Further, the upper plate is shaped to create turbulences in the air to cause other impurities to flow over and be caught by the flypaper-like material.
