If you're not sure how often to change your vehicle’s cabin air filter, we recommend reviewing the manufacturer's specifications and recommendations for your vehicle. Many drivers choose to replace their filter once a year, or when they notice poor performance or limited airflow, but cabin air filters can be replaced as often as needed for maximum performance. Cabin air filters are vehicle-specific, meaning the products, installation, and location of the filter will depend on the vehicle you're driving. For replacement intervals specific to your vehicle, check your owners manual.
How to Change a Cabin Air Filter
The cabin air filter in your vehicle is designed to trap debris and contaminants from the air outside of the vehicle before airflow enters the cabin. This filtration process ensures that the air brought into your vehicle’s cabin is almost completely free of allergens, pollutants, and debris, which not only makes the air you breathe while driving, but can also keep your interior cleaner. Dirty cabin filters restrict clean air flow through the vehicle's ventilation system, impacting performance of your vehicle’s A/C system. Clogged cabin air filter symptoms can include:
- Reduced or limited airflow through the vents
- Odors during heat or A/C system operation
- Difficulty clearing fog from the windshield
- Lack of A/C system performance
It’s important to change your cabin air filter according to the recommended filter replacement intervals in your owners manual to keep the vehicle’s heating and cooling system operating as well as possible. While many drivers choose to change their cabin air filters once a year, it’s important to follow the recommended replacement intervals, especially if you drive in dusty or polluted environments. When it’s time to change your cabin air filter, stop by O’Reilly Auto Parts to find the right replacement filter for your vehicle.
