An apparatus for filtering grease laden fumes in the space above a cooking appliance, including a hood, a supply air plenum and an exhaust air plenum on each side of the hood, a source of air under pressure being connected to a supply air transition duct connected by an air supply transition duct coupled to an opening in the air supply plenum, the supply air plenum being provided with perforated balancing plates which perform the function of modulating the incoming air to flow in a particular manner, and further being provided with perforated deflector pairs of overlapped plates positioned below the balancing plates, to additionally modulate the air flow paths, so that straight paths of air flow move into the interior of the hood above the cooking appliances and then pass through filters which remove grease particles as the exhaust air moves through the filters into the exhaust air plenum. An equalizer vane member is secured to shroud the exhaust air passing through the filters, the equalizer vane member being provided with an exhaust opening which communicates with an exhaust air plenum, the exhaust air under said equalizer vane member being conducted toward the exhaust opening which registers with an opening in an exhaust air transition duct which is coupled to an exhaust duct communicating with a source of exhaust suction.
