Abstract
An operating room filter system connectable to a surgical body gas evacuator, such as a trocar, that includes a carbon monoxide filter media that removes carbon monoxide from a surgical waste gas. In addition, the inclusion of further filter media upstream of the carbon monoxide filter media inhibits the saturation of the carbon monoxide filter media to thereby provide an extended life to the filtration system.
