Anti-fogging car mask

In cold weather, water vapour exhaled by a vehicle's occupants causes obscuration of windows when it condenses. This is mainly a problem in the first few minutes of driving, when the engine is cold and there is no spare heat to divert to the ventilation system.

However, with the new BorgCo car mask, the problem can be greatly alleviated. Simply place the mask to cover the nose and mouth, and breathe normally. Air is inspired from the interior of the vehicle via a one-way valve; expired air passes out through another one-way valve into a lightweight tube provided with trace heating to prevent condensation. This warm, moist air is routed to the exterior of the vehicle through a vent port.

Once the car is warm, remove the mask and continue as normal.
