An exhaust hood for commercial or institutional kitchens. The hood is designed to capture individually each of the plumes emanating from diverse cooking or heating devices disposed beneath the hood and includes means for minimizing the quantity of air removed from the atmosphere ambient to, but outside the hood, this means including a plenum within the hood and individually sized entrance openings into compartments defined above each of the cooking or heating devices and through which ambient air is drawn at a minimum capture velocity for that plume anticipated to be generated by the heating or cooking device that is associated with each compartment. A method for carrying out the invention is disclosed.
