A filter for filtering air for an internal combustion engine and a method of operation are described herein. The air pre-cleaner (100) is configured to move ionized particles (128) toward an inner wall (126) of the air pre-cleaner (100) using electrostatic attraction or repulsion, where the particles (128) ultimately exit the air pre-cleaner (100) through the particle outlet (120). Particles (128) are ionized using a positively charged plate and a negatively charged plate. The positively charged plate generates a positively charged field (134A), thereby generating positive ions that ionize particles (128) in the air to positively charge. The negatively charged plate generates a negatively charged field (134B), thereby generating negative ions that ionize particles (128) in the air to negatively charge. The air pre-cleaner (100) may also include a cyclone section (104) that rotates the air about a central axis of the air pre-cleaner (100) to apply a centripetal force to the particles (128). The centripetal force and the electrostatic force act together to filter air.
