1. A V-Bank filter apparatus, the apparatus comprising:
a pre-filter through which an airflow passes, wherein the pre-filter includes a pre-filter electrical conductor configured to ionize particles in the airflow as the particles enter the pre-filter; and
a main filter including one or more sections that receive the airflow after the airflow passes through the pre-filter, each one of the one or more sections including:
a metallic shield connected to a ground potential through which the airflow passes into the section;
an electrical conductor configured to be connected to a voltage source that provides a voltage to the electrical conductor, the electrical conductor located within the section and the electrical conductor being different from the pre-filter electrical conductor, the voltage provided to the electrical conductor creating an electric field that ionizes particles included in the airflow passing through the section; and
a plurality of filter elements, each filter element including a filter media disposed between a first filter grid that is connected to the ground potential and a second filter grid that is electrically isolated from the first filter grid, wherein:
the electric field is disposed between the second filter grid and the first filter grid based on the second filter grid being charged to a potential and the first filter grid being connected to the ground potential when the voltage is provided to the electrical conductor by the voltage source, and
the ionized particles in the airflow passing through the section are trapped in the filter media when the second filter grid is charged to the potential.
