The present disclosure is directed methods and apparatus of a V-Bank filtration system capable of maintaining desired air flow rates while effectively filtering the air. These methods and apparatus charge particles and then capture those particles in a filter medium. Once captured in the filter medium, micro-organisms are exposed to high energy electric fields that may degrade and ultimately destroy the captured micro-organisms. Electric fields generated within portions of the V-Bank filter apparatus may also be contained within the portions of the filter apparatus based on exterior parts of these portions being grounded at Earth ground potential. Magnetic fields (or electro-magnetic fields) associated with the generated electric fields may also be contained within the portions of the apparatus based on the exterior parts of these portions being grounded.

An ion filtration air cleaning device for cleaning air by use of electrostatic ion attraction. Air having suspended particles is drawn into the device through an inlet by a fan. An ionization source near the inlet generates ions. Electrical charge transfers from the ions to the suspended particles. The fan pushes the air and suspended charged particles toward an outlet. A filter located adjacent to the outlet operates by electrostatic attraction and filters the charged particles from the air, allowing cleansed air to be released from the device, with a reduced level of charged particle emission.
