What Does A Cabin Air Filter Do? Your car has a cabin air filter that helps clean the air you breathe. The cabin air filter can catch particles like pollen, dust and pollutants. Over time, the cabin air filter can become clogged with dirt and debris. The heat and AC in your car are affected by the air flow through the cabin air filter.
