If your car becomes dusty faster than usual, or if the cabin smells unpleasant with no obvious cause, then it might be time to replace your Chevy cabin air filter.  Changing the filter regularly is vital, as it plays an important role in keeping contaminants out of the car.


What Does Your Chevy Cabin Air Filter Do?

Keeps Your Interior Clean

Catching dust and dirt is part of your cabin air filter’s job. This helps keep those contaminants out of your car, keeping it cleaner. With no dust or dirt buildup, you don’t need to wipe down the surfaces to get rid of dust as often, and it helps the interior last longer by keeping it free of things that could damage it.


Keeps Contaminants Out

Some things that your air filter keeps out can be hazardous. Twigs, rodent droppings, soot, leaves, and insects are just some of the more harmful things that your filter may keep at bay. Different filters are designed to keep different contaminants out of the car, but they all work to keep the interior as contaminant-free as possible.


Keeps You Safe and Healthy

By keeping contaminants out of the cabin, the air filter doesn’t just keep you safe from breathing in harmful and unhealthy substances. It can also keep pollen and other allergens out of the car. Keeping allergens out can improve your safety by reducing symptoms such as blurry vision and sneezing. Dealing with these symptoms while driving can be distracting and make driving more dangerous.


How Often Should You Change Your Cabin Air Filter?

How often your air filter needs to be changed varies depending on several factors, including how much you drive and the environments you drive in most often. Learning the signs that you need to change the air filter, or asking the technicians at your local dealership for advice, can help you get a good idea of how often you will need to change yours.

Your owner’s manual may also recommend how often you need to change the air filter. For example, a recommendation from the owner’s manual of a 2025 Chevy model says to change the air filter every 36,000 miles or every 24 months.


What Happens If You Don’t Change Your Cabin Air Filter?

Not getting your cabin air filter changed can lead to more dust buildup in your car, weak airflow from the vents, and a bad smell that doesn’t go away, no matter how much you clean your cabin. The smell could be mildew or other bacteria in your vents, and your old, clogged filters can’t filter it out properly.
