[NicoleLee]

The cabin air filter in a Volkswagen Passat is located inside the glove compartment in front of the front passenger seat. To replace the cabin air filter, you need to remove the glove compartment in front of the front passenger seat to access and replace the filter. It is generally recommended to replace the filter during spring or autumn, as the air conditioning is used more frequently in summer, making the filter more prone to dirt accumulation. Below are the functions of a car's cabin air filter: 1. Filters the air to ensure that the air entering the cabin is purified. 2. Blocks pollen, dust, and other particulate pollutants in the air. 3. Absorbs odors, carbon compounds, sulfur compounds, and other airborne contaminants. 4. Filters harmful gases such as exhaust fumes and has strong moisture absorption capabilities to prevent the windshield from fogging up. 5. Maintains clean and fresh air inside the car cabin, reducing bacterial growth and ensuring the health and safety of passengers and drivers.
