A filter structure for use within a filter system for capturing airborne contaminants and adsorbing odor. The filter structure includes a filtration medium of activated carbon fibers spun into an activated carbon mesh network filter for adsorbing airborne odors such as those transported by smoke and for capturing extremely small airborne particulate. A preferred filter structure includes, in order, a macro filter for capturing larger airborne particulate, an ULPA filter for capturing smaller airborne particulate, and an activated carbon mesh network filter formed of activated carbon fibers spun into a fiber mesh for adsorbing airborne odors and for capturing extremely small airborne particulate not retained by the macro or ULPA filters. The filter structure here defined provides superb particulate removal as well as odor adsorption, and is especially useful in thermal surgical procedures where smoke evacuation is a major goal in working toward maintenance of a safe operation site.
