a secondary air flow chamber adjacent the primary air flow chamber; an air flow diverter between the primary air flow chamber and the secondary air flow chamber that diverts a portion of air flow from the primary air flow chamber and into the secondary air flow chamber, with the diverted portion of the air flow flowing back into the primary air flow chamber; and a tray configured to retain an aromatic agent, the tray movable into and out of the secondary air flow chamber to selectively place the aromatic agent in contact with air flowing through the secondary air flow chamber to aromatize the air before flowing back into the primary air flow chamber. ## Claims ### Claim 1 An outlet for a forced air system of a vehicle comprising: a primary air flow chamber defining a primary air flow path from an entrance to an exit;
