Abstract
An air filtration system includes a frame directing an airflow through the air filtration system and a power supply. An ionization array is located in the frame across the airflow and connected to the power supply. The power supply provides a first voltage to the ionization array. A field wire is located in the frame downstream from the ionization array and is energized to a second voltage only by an electrical energy discharge from the ionization array. A method of operating an electrically enhanced air filtration system includes energizing an ionization array, located across an airflow through the air filtration system, to a first voltage via electrical power supplied by a power supply. Electrical energy is discharged from the ionization array into the airflow. A field wire downstream of the ionization array is energized to a second voltage only by the discharge of electrical energy from the ionization array.
