How Often to Change the Cabin Air Filter
Changing your cabin air filter matters. This filter cleans the air that enters your vehicle's cabin area through the ventilation systems. It gets rid of dust and other tiny bits you don't want to breathe. Plus, some advanced filters eliminate odors and other harmful contaminants that are common in traffic.
If you don't change the cabin air filter, your car's AC and heat might not work as well, and it could cause loud fan noises. It's good practice to change it regularly so you can enjoy a comfortable ride every time. In this article, we’ll discuss the best interval for replacing the cabin air filter and the factors that impact the cabin air filter lifespan.
When to Replace Your Cabin Air Filter?
It's best to change the cabin air filter at least once a year, or as recommended by your vehicle's manufacturer. If you drive in dusty or polluted areas, or live in a region with frequent sandstorms, you may need to change it even more often. It's also a good idea to replace your cabin air filter if you notice that your air conditioning or heating system is not working as efficiently, if there are bad odors in your car, or if the fan is noisy.
When replacing the cabin air filter, be careful not to get debris into the blower motor. If your fan is louder than usual after installing the new filter, it's possible that some debris fell into the system and you should see a professional to fix the problem.
Signs You Need to Change Your Cabin Air Filter
If you're not sure if it's time to change your cabin air filter, the following problems can signal a clogged filter that needs replacing:
- Reduced airflow from the vents when the HVAC system is set to high
- Dust in the cabin
- Loud fan noises
- Bad odors coming through the ventilation system
