The cabin air filter is often overlooked as drivers maintain the vehicles they own. Unfortunately, this can lead to issues when you don't replace it after it has a build-up of dirt and debris.
One of the main reasons you'll need to be proactive about replacing the cabin air filter is that it is responsible for keeping your cabin clean. It keeps odor, smog, and even twigs out of the vehicle. You don't have to worry about debris getting into the cabin through the vents.
