Reasons to change your air filter

You should change the cabin air filter of your 2020 BMW M850i for several reasons:

• Cleaner air quality inside the car: The cabin air filter helps to remove pollutants, dust, and other allergens from the air inside the car, which improves the air quality for everyone on board.
• Extending the life of the HVAC system: The cabin air filter also helps to keep the heating and air conditioning system running smoothly, which helps increase the efficiency of the system.
• Improving the air quality outside the car: A clean air filter can also help improve the air quality outside the car by filtering out airborne contaminants.
• Protecting the engine: A dirty or clogged air filter decreases the airflow to the engine, which can damage the engine over time.
• Better engine performance: A clean air filter allows for a greater amount of air to reach the engine, which can improve overall performance and fuel efficiency.

If you replace your air filter on a regular basis, you can ensure that your BMW M850i engine and HVAC system are running efficiently, and that the air inside and outside the car is clean and healthy.

Similarly, if you often drive on dirt or gravel roads, or if you use your 2020 BMW M850i for off-roading, change your air filter more often.

It’s also important to pay attention to the signs that the filter needs to be changed, including:
