An exhaust-only type of kitchen exhaust hood is provided with removable fume-guide plate upstream of the in-hood grease filters. The plates are shaped to provide a forward flow of fumes from the rear of the hood forward over the cooking unit toward the front lip of the hood. A slot is provided between the front edge of the plate and the front wall of the hood whereby the air flow into the hood accelerates around the front edge of the plates to provide a flow rate of approximately 200 feet per minute at the front edge of the hood. Slots are provided between the hood ends and adjacent side edges of plates next to the ends. The plates are movable to facilitate changing of filters.
