An inlet air filtration system for a gas turbine includes, in an exemplary embodiment, an air plenum, and a plurality of filter elements mounted inside the air plenum, with each filter element including a support structure. The inlet air filtration system also includes a plurality of electrodes positioned proximate the plurality of filter elements, where the electrodes are coupled to a power source which supplies a voltage to the electrodes. The voltage is sufficient to establish an electrostatic field between the electrodes and the filter elements, and at the same time, the voltage is sufficient to produce a corona discharge from the electrodes.
