Abstract: Example embodiments of the described technology provide an exhaust hood for removing effluent plumes produced by cooking activity. The exhaust hood may comprise an exhaust fan operable to create a region of negative pressure beneath the exhaust hood for drawing air entraining the effluent plumes into the exhaust hood. The exhaust hood may also comprise one or more plenum chambers in fluid communication with the exhaust fan. The exhaust hood may also comprise one or more orifices in fluid communication with the one or more plenum chambers, the orifices located along a front edge of the exhaust hood. The exhaust hood may also comprise a filter for cleaning the air drawn into the exhaust hood such that air entraining the effluent plumes drawn into the exhaust hood by the exhaust fan is drawn through the filter to yield cleaned air. The exhaust hood may deliver at least a portion of the cleaned air into the one or more plenum chambers.
