How often should I change the air filter in my Kia Niro?

I have owned my Kia Niro for over 2 years now and have not yet changed the air filter. I am unsure of how often this should be done and if there are any signs to look out for that indicate it needs to be changed.

As a general rule, it is recommended to change your air filter every 12,000-15,000 miles or every 12 months, whichever comes first.

If you frequently drive in dusty or polluted environments, it may be necessary to change the air filter more frequently, such as every 6,000-10,000 miles.

You may also notice a decrease in fuel efficiency or a musty smell in your car, which could be signs that your air filter needs to be changed.
