Patent ID: 7384456

Claim:
An air purification device arranged to treat aerosol particulates carried in a fluid stream passing through the device, the air purification device comprising: a ionizer arranged to receive the fluid stream, the ionizer including a discharge electrode and a receptor electrode; at least one electrostatic filter located downstream of the ionizer such that the fluid stream passes through the electrostatic filter after passing through the ionizer, the electrostatic filter including first and second electrodes; a plurality of frame members arranged in a stack, the frame members being arranged to define a flow channel through which the fluid stream passes and to support components of the air purification device that receive the fluid stream; a plurality of rods that pass through the frame member stack, wherein a first one of the rods serves as an electrical power source at a first potential and a second one of the rods serves as an electrical power source at a second potential; and a plurality of electrical connectors that each electrically couple an associated one of the electrodes to an associated rod.
