If the car's outer vents are aimed at the side windows then misting can be eliminated.
If the car's outer vents are aimed inwards then, in a hot climate, a comfortable environment is obtained in the passenger compartment.
Opening and closing the air vents
Air vents for the front seat:

The longer the white lines on the thumbwheel that are visible, the higher the air flow.
