During a vehicle repair, you might not be surprised if a mechanic tells you it’s time to replace your air filters — however, you might be confused if they tell you you need to replace two. Your car actually has two separate air filters: a compartment air filter and an engine air filter. Each filter is designed to prevent harmful pollutants from entering your vehicle. So, what’s the difference between an engine air filter and a compartment air filter?

What are cabin air filters?

When you think of an air filter, you probably associate it with the device used to clean the air you breathe. This is closely related to the function of your cockpit air filter. This filter is located under your dashboard and prevents dust and allergens from circulating through your car’s heating and cooling system. Controlling pollutants passing through your vehicle can be a challenge, so your cockpit air filters work hard to keep your driving experience safe, comfortable and healthy.

How do you know when you need to change your cab air filter

The pace of air filter replacement depends on your vehicle’s year, make and model, and your driving habits. You may start to notice a change in air quality in your car, although the change may be subtle and difficult to detect. In general, you need to replace this filter every 20,000 to 30,000 miles. For a more accurate estimate, check your owner’s manual or talk to your local mechanic. If you have allergies, have respiratory sensitivities, encounter bad pollen in your area, or live in a smoggy city, you may need to change your cockpit air filter more frequently.

What is an engine air filter?

As the name suggests, this air filter is located inside your engine to prevent harmful debris from entering the system. While you may scoff at such a small service, regularly replacing your engine air filter is affordable and can save you thousands of dollars in engine damage. It also helps improve the performance and efficiency of your vehicle, enabling you to save money at the pump. That’s why check for clean engine filters during your annual emissions check and annual vehicle inspection.

How do you know when you need to change your engine filter

As with your cockpit filter, the pace at which you need to replace your engine air filter depends on your vehicle type. Certain environmental and driving factors can also affect how often you need to change the engine filter. For drivers who regularly drive on dirt roads or live in cities with too many pollutants, these hazards can quickly overwhelm your engine filters. You may notice a decrease in fuel efficiency and drivability due to expired engine filter replacement. This service is typically required every 12,000–30,000 miles. If you are still unsure whether or not an engine filter needs to be replaced, check with your local vehicle service specialist.
