How often should the air filters be replaced in a BMW 3 Series?

I have a 2015 BMW 3 Series and I'm wondering how often I should replace the air filters. I've been told different things, some say every 30,000 miles, some say every 60,000 miles. What's the recommended interval?

It is recommended to replace the air filters in your BMW 3 Series every 30,000 miles. However, this can vary depending on your driving habits and the environment you drive in. If you frequently drive in dusty or polluted areas, it's best to replace them more often.

I would recommend replacing the air filters every 30,000 miles, as stated by BMW. Regular replacement can improve engine performance and fuel efficiency.
