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.
Claims3
A method of removing contaminant particles and VOC from an airstream, which comprises:
- generating ions to charge the particles and generate ozone,
- collecting the charged particles downstream of the generating, and
- catalytically removing VOC and ozone from the airstream downstream of the collecting of the particles.
