The cabin exhaust device ventilates vehicles provided with retractable windows and mounts on a portion of the vehicle, preferably on a door frame or in an opening between a window panel and a window frame. The cabin exhaust device comprises a squeegee and a ventilation panel having an air dam, a first portion, and a second portion, wherein the first and second portions are provided with angularly oriented apertures, thereby creating a vacuum on the vehicle's interior side. The first and second portions are outwardly convexed, thereby facilitating the creation of a pressure differential between the vehicle's interior and its exterior, thus forcing the air and other contaminants out from the vehicle's interior.
