Purpose of the Cabin Air Filter
Your cabin air filter captures dust, pollen, smog, and other potentially harmful particles as air passes from the outside to the inside of your vehicle so that the air you and your passengers breathe is cleaner and less harmful. A clogged and dirty air filter means allergens from the outside will not be properly cleaned, and airflow may be compromised. You have an air filter in your home that performs the same function, trapping particles, pollen, dust, smog, and dirt before they flow into your home where it can cause respiratory distress.
Signs Your Cabin Air Filter Needs to be Replaced
When your filter becomes too clogged with trapped particles, airflow is affected. As your filter gets too clogged, the airflow entering the cabin will be weak, and the air that does get in will be stale and musty. You’ll notice increasing amounts of dust that settle on the dashboard and other surfaces. If you’re noticing these signs already, you need to have your air filter replaced.
How Often Should My Cabin Air Filter Be Replaced?
If you don’t have any of these symptoms, how do you know how often to replace the filter? The short answer is it depends; your vehicle’s make, model, and year can affect the interval in which it should be changed because of changes in the design. Generally, most cabin air filters should be changed every 15,000-30,000 miles. The best practice is to check your vehicle owner’s manual. Your manual should have a schedule for all your vehicle maintenance needs and if you’ve lost your manual or never had one, our certified automotive technicians at Victory GMC of St. Joseph will be happy to make recommendations for you.
Benefits of Regular Maintenance
Your cabin air filter is usually located behind your glove compartment in your vehicle or under the hood. The cabin air filter plays an important role in the comfort and safety of you and your passengers. Whenever you run the heat or air conditioning in your vehicle, it draws air from outside the vehicle and the air is drawn through the cabin air filter where dust, mold spores, pollution, and pollen from the outside are all trapped so the air entering your cabin is cleaner and fresher when you and your passengers breathe it in. When you have regular air filter service as recommended, the quality of the air in your vehicle’s cabin is better.
