Where is the cabin air filter located in a BMW 1 Series?

[DeDylan]

The cabin air filter in a BMW 1 Series is typically located inside the glove compartment in front of the front passenger seat. To replace the cabin air filter, you'll need to remove the glove compartment in front of the passenger seat to access and replace the filter. It's generally recommended to perform the replacement during spring or autumn, as the air conditioning is used more frequently in summer, which can lead to faster filter contamination. The functions of a car's cabin air filter include: 1. Filtering air to ensure purified air enters the vehicle cabin; 2. Blocking airborne contaminants like pollen, dust, and particulate matter; 3. Absorbing odors, carbon compounds, sulfur compounds, and other airborne pollutants; 4. Filtering harmful exhaust gases while providing strong moisture absorption to prevent windshield fogging; 5. Maintaining clean cabin air to inhibit bacterial growth, ensuring passenger health and driving safety.
