Do I really need to replace my air filter?

I have a Nissan Patrol and I'm wondering if I really need to replace my air filter. It doesn't seem dirty or clogged, but I've heard that it's important to change it regularly. Can I just clean it instead?

Yes, it is important to replace your air filter regularly to ensure proper airflow and engine performance. Cleaning it may not be as effective.

You can try cleaning your air filter, but if it still looks dirty or clogged, it's best to just replace it. It's a relatively inexpensive maintenance task.
