Understanding the difference between your car air filters is essential for maintaining peak performance and air quality. So, when it comes to engine air filters vs. cabin air filters, what’s the difference between these car air filters?

The cabin air filter purifies air circulating through the HVAC systems, ensuring a clean interior environment. Conversely, the engine air filter shields the engine from dirt, dust, and other contaminants. Join us as we explore these crucial components and learn when and how to replace them effectively. If you notice any problems with your engine or cabin air filter, schedule a service appointment with our certified technicians for a thorough inspection without delay.

 

 

Engine Air Filter vs. Cabin Air Filter: How Many Air Filters Does a Car Have?

How many air filters does a car have? Most vehicles have two air filters: the engine air filter and the cabin air filter. The engine air filter cleanses the air circulating through the engine, protecting it from bugs, dirt, and dust. Meanwhile, the cabin air filter keeps the air inside the vehicle fresh and pollutant-free whenever the AC or heating systems are in use.

Cabin Air Filter vs. Engine Air Filter: What Happens If You Don’t Change Them?

  • Engine Air Filter: A clogged engine air filter limits airflow to the engine, causing poor fuel economy, reduced performance, and potential engine damage. It can also lead to failing your NC emissions inspection due to decreased fuel efficiency.
  • Cabin Air Filter: A blocked cabin air filter restricts airflow to your car’s heating and cooling system, straining it and potentially causing air conditioner and heater malfunctions.

Regularly changing these filters can prevent expensive repairs, saving you hundreds or even thousands of dollars in the long term.
