Can Smoking in the Car Be Exhausted by Using the External Air Circulation?

Smoking in the car with external air circulation on. Turning on the external air circulation mode allows outside air to flow into the car while also carrying the smoke out. It is recommended to open the windows when smoking in the car, as this helps the smoke to quickly dissipate with the airflow. If the car makes a vibrating noise when the air conditioner is turned on, there might be several reasons: 1. Dirty air filter: A dirty air filter can cause excessive noise and abnormal sounds. 2. Debris in the blower fan blades: Debris inside the blower fan blades can lead to abnormal sounds. You can check this by turning on the blower without starting the engine to see if the noise occurs. If it does, the issue is likely with the blower. 3. Fan problem: Deformed fan blades or a damaged fan motor in the car's air conditioning system. 4. Worn clutch bearing: A worn clutch bearing inside the air conditioning pump can cause the engine noise to increase when the air conditioner is on. This component cannot be replaced separately and requires the replacement of the entire air conditioning pump assembly.

To be honest, having driven for over a decade myself, I know smoking in a car can leave serious lingering issues. Using the recirculation mode does draw in some outside air to help dilute the smoke and direct it outward, which works much better than the internal circulation mode. But here's the problem—smoke particles are extremely fine and cling to fabric seats, headliners, and dashboards, making them nearly impossible to fully clean. The recirculation mode can't tackle those deep-seated pollutants either. My advice is, if you absolutely must smoke in the car, crack the windows while using the recirculation mode to speed up airflow and vent the smoke faster. Plus, the enclosed car environment traps odors stubbornly after smoking, often requiring professional cleaning to remove. Long-term smoking also clogs the cabin air filter, affecting ventilation. In short, it's best to avoid smoking in the car altogether.

From my perspective, smoking inside the car is really not recommended, even if you turn on the external circulation mode. External circulation draws in fresh air from outside, which can somewhat reduce smoke concentration and push some smoke outward, but it's impossible to completely eliminate it – smoke contains particles and volatile substances that adhere to the AC ducts and interior materials, eventually forming stubborn odors over time. Additionally, the confined space of a car poses significant health risks, such as secondhand smoke residue containing carcinogens that can affect children or other passengers. I strongly suggest opening windows to enhance ventilation while smoking, or better yet, stepping outside to smoke. Regularly replacing the cabin air filter can help somewhat, but the key is to protect yourself and prevent your car from becoming a pollution source.

Tried smoking in the car with the air recirculation off—it helps but isn't a miracle. The external air intake dilutes the smoke, and some gets expelled, especially at higher speeds, but smoke particles still cling to the interior. Here's the straight solution: cracking a window while keeping the recirculation off works best. Ventilate immediately after smoking to prevent odor buildup. Regularly check the cabin air filter—it's affordable but crucial.
