Abstract: Presented are a method and apparatus for evacuation. An exemplary fluid evacuation system includes a surgical apparatus having a fluid conduit therethrough. The system further includes a vacuum tube fluidly coupled with the fluid conduit, and an electrostatic precipitator fluidly coupled with the fluid conduit. Additionally, the system includes a vacuum source fluidly coupled with the vacuum tube, wherein the vacuum source is operable to create a flow of fluid through the fluid conduit, the vacuum tube and the electrostatic precipitator.
