Similarly, what does a demister do? A demister is a device often fitted to vapor–liquid separator vessels to enhance the removal of liquid droplets entrained in a vapor stream. Demisters may be a mesh-type coalescer, vane pack or other structure intended to aggregate the mist into droplets that are heavy enough to separate from the vapor stream.

In this manner, how do you use a demister in a car?

Hit the car windscreen demister button without air-conditioning and the ventilation system will try to warm up the windscreen, by blowing warm air at it and/or by running an electric current through a thin wire stuck onto the screen (more common in rear windscreens) to warm up the wire, and eventually, the window.
