Abstract
Apparatus and method for removal of particles and VOC from an airstream, in which particles carried by the airstream are charged by a corona ionizer and then collected by an electrically enhanced filter downstream of the ionizer. A catalytic filter downstream of the electrically enhanced filter removes VOC as well as ozone generated by the ionizer.
