How often should I change the air filter in my Toyota Highlander?

I recently bought a Toyota Highlander and I'm unclear on when to change the air filter. How often should I do this and is it something I can do myself or should I take it to a mechanic?

You should change your air filter approximately every 12,000 to 15,000 miles or every 12 months. This may vary depending on your driving habits and the condition of the roads you drive on.

It's a relatively simple process to change your air filter yourself. However, if you're unsure or uncomfortable doing it, it's always best to take it to a mechanic to ensure it's done correctly.

If you frequently drive on dusty roads or in areas with high levels of pollution, you may need to change your air filter more often. It's important to regularly check the condition of your air filter and replace it as needed.
