Should You Use Internal or External Air Circulation When Smoking in a Car?
3 Answers
When smoking in a car, it is advisable to use the external air circulation mode. This allows outside air to flow into the car and helps carry the smoke out. Relevant information is as follows: Internal Circulation Mode: When smoking in a car, it is recommended to open the windows to allow the smoke to quickly dissipate with the airflow. The internal circulation mode helps maintain warmth in winter and keeps the car cool in summer. Activating the internal air circulation mode aids in rapidly lowering the interior temperature and prevents outside air and odors from entering the car. Consequences of Prolonged Use of Internal Circulation Mode: Extended use of the internal circulation mode can cause window fogging. If window fogging occurs, you can select the defogging mode on the air conditioning system. When defogging is activated, the dehumidification function works, and the fan speed increases. Setting the internal air circulation mode button to external circulation, increasing airflow, and raising the temperature can quickly defog the windshield and front side windows.
As a veteran driver with over a decade of experience, I highly recommend turning on the external air circulation mode when smoking in the car. This is because smoking generates significant smoke odors and particulate matter. Using internal air circulation causes the smoke to circulate and accumulate inside the vehicle, resulting in stale, unpleasant air and potentially leaving stubborn odors on seats or interior surfaces. In contrast, external air circulation allows fresh air to flow in from outside, diluting the smoke smell and helping to quickly expel it from the vehicle, making breathing more comfortable. However, smoking while driving for extended periods is unhealthy—it's best to smoke less or finish smoking outside before entering the car. To maintain air quality, regular cleaning of the air conditioning filter is also essential. For even better results, try cracking the window slightly while using external air circulation.
As a father of two, I'm particularly concerned about the cleanliness of the air inside the car. Never turn on the recirculation mode while smoking, as cigarette ash and harmful gases will accumulate in the enclosed space, posing risks to family health, especially for children with sensitive respiratory systems. I always use the fresh air mode to let outside air flush in and disperse the smoke, reducing residue. If the automatic air conditioning is on, you can press the fresh air button to assist with temperature regulation. But honestly, it's best to quit smoking or smoke when safely parked on the roadside to avoid these issues. Remember, poor air quality is not only unpleasant but also affects driving concentration, so developing good habits is key.
