Closed loop smoke filtration system

A closed loop filtration system comprising:

• a first trocar configured to supply a fluid into a body cavity;
• a second trocar configured to discharge the fluid from the body cavity;
• a power supply;
• first and second ionizer units electrically coupled to the power supply;
• and
• a filter cartridge including:
• an outlet in communication with the first trocar;
• an inlet in communication with the second trocar;
• a first electrode disposed downstream of the inlet of the filter cartridge, the first electrode electrically coupled to the first ionizer unit to electrically charge airborne particulate matter passing through the first electrode;
• and
• a second electrode disposed downstream of the first electrode, the second electrode electrically coupled to the second ionizer unit and configured to attract the airborne particulate matter that is electrically charged by the first electrode.
