Maintaining the cabin air filter in your GMC is crucial for ensuring a clean and healthy environment inside your vehicle. Signs that it's time for a replacement include reduced airflow through your Hvac system and an unpleasant odor when the air is running. To extend the lifespan of your filter, avoid parking under trees where debris is likely to accumulate. When selecting a new cabin air filter, consider the two common types—standard particulate filters for dust and pollen, and activated carbon filters that also absorb odors and gases. Always opt for high-quality, OEM-spec materials to ensure a perfect fit and optimal air quality. Installation is straightforward, but always ensure the arrow on the filter matches the airflow direction for peak performance.
