A combined window-screen and ventilation system includes first and second non-corrosive conduits that are conjoined to the vehicle's existing air circulating system. The conduits are in fluid communication with the air circulating system such that air can flow therethrough. The conduits terminate rearward of a vehicle's front window and are provided with spaced apertures so that air is discharged towards side door window openings and a sunroof opening. Window screens are interfitted within the door window and the sunroof openings. A mechanism is included for circulating stagnant air within the vehicle. The air circulating mechanism is seated within the vehicle interior, is conjoined to the sunroof, is independently and contemporaneously operable with the vehicle air-circulating system, and is remotely operable up to 50 feet away, for example.
