A scent dispenser includes a housing, holder having scent cartridge receiver(s) to removably hold scent cartridges, baffle(s) with a port which is positionable, actuator(s) (e.g., stepper motors), and a control subsystem that drives the actuators to position the baffles to selectively dispense scent from the scent cartridges. The scent cartridges can have passages, at least some of which contain scent media, and optionally one passage without scent media. The housing can be cylindrical and fittable in a cup holder of an automobile. The scent dispenser can have vents at a bottom, a grille at a top, and an air mover (e.g., fan) to create an air flow from the vents through the grille, passing through any scent channels which are aligned with the ports to dispense scent. One or more substrates (e.g., printed circuit boards) can have apertures (e.g., large central passage) to facilitate the air flow.
