Abstract
A surgical treatment system for contaminated air streams having particulate contamination, polar contamination and/or nonpolar contamination in the gas or vapor stream. A surgical smoke plume treatment system and method provide or define a multi-stage treatment process that mechanically filters the air stream, followed by nonpolar decontamination and then polar decontamination or treatment. The system may be used stand alone or incorporated and used with other surgical instruments or incorporated into an air handler adapted to decontaminate an air stream. A desiccant may optionally be used to remove water from the air stream.
