This disclosure relates to an improved exterior adjustable rearview mirror for motor vehicles, with air flow apertures designed and arranged for the removal of moisture, dust, debris and the like from the viewing surface of a rearview mirror mounted therein. The exterior adjustable rearview mirror attached to the front side window, in a manner known per se, consists of a fixed rigid rearview mirror housing with a rearwardly opening providing visibility to an adjustable rearview mirror therein. An air intake aperture is formed on the forwardly directed wall of the rearview mirror housing structure, with respect to the direction of travel of the motor vehicle. The air intake aperture serves to direct the flow of air through a vertical air compression chamber within the rearview mirror housing structure. Hence, the flow of air travels out through the air exhaust aperture located above the viewing surface of the rearview mirror. The flow of air exiting the air exhaust aperture applies a force on the viewing surface of the rearview mirror in such a manner whereby moisture, dust, debris, and the like is forced in a vertical direction off the viewing surface of the mirror, as the motor vehicle with the attached exterior adjustable rearview mirror travel in a forward direction. In addition, the design of the air compression chamber together with the moisture sump depression and the moisture weep duct will remove airborne moisture which may be captured within the device. This moisture is removed and is not distributed onto the viewing surface of the rearview mirror.
