Why Does the Car Air Conditioner Smell Like Rotten Eggs?

[StSienna]

This situation is caused by the odor from an air filter that hasn't been replaced for a long time. Simply replace the filter in a timely manner. Precautions for replacing the air filter: If the airflow from the air conditioner is significantly reduced, the air filter may be clogged; the cleaning frequency depends on road conditions (dusty roads, etc.). It is advisable to clean it earlier; the air filter should be correctly installed in its position. Using the air conditioner while the filter is removed may degrade dustproof performance and affect the air conditioner's performance. Function of the car air filter: The air filter acts like a 'mask' for the car, filtering out dust and impurities from the air to ensure the engine runs normally. It also prevents bacteria growth in the air intake, which can cause odors inside the car and even affect the health of the passengers.
