Car air filters are essential components that protect your vehicle and your health from harmful pollutants. They filter out dust, dirt, pollen, allergens, odors, and other contaminants from the air that enters your engine or your cabin. In this article, we will explain the difference between engine and cabin air filters, how often you should change them, and how to do it yourself or with professional help.
What is the difference between engine and cabin air filters?
The main difference between engine and cabin air filters is their location and function. The engine air filter is located near the front of your vehicle under the hood, inside a sealed box. It cleans the air that your engine uses for combustion, which affects your fuel efficiency, performance, and emissions. The cabin air filter is usually located inside the passenger compartment, behind or near the glove box. It cleans the air that you and your passengers breathe inside the car, which affects your comfort, health, and air quality.
Another difference between these two types of filters is their size and design. The engine air filter is usually larger and more complex than the cabin air filter, because it has to handle a higher airflow and trap larger particles. The cabin air filter is smaller and simpler, but it has smaller holes and sometimes contains carbon layers to filter out finer particles and neutralize odors.
How often should you change your car air filters?
The frequency of changing your car air filters depends on several factors, such as your vehicle model, driving conditions, climate, and personal preference. However, a general rule of thumb is to change your engine air filter every 15,000 miles or once a year, and your cabin air filter every 25,000-30,000 miles or every two years. You should also check your owner’s manual for specific recommendations from your manufacturer.
Some signs that indicate that you need to change your car air filters are:
- Reduced or weak airflow from your vents
- Unpleasant or musty odors in your car
- Increase in fuel consumption or decrease in performance
- Noise or whistling from your air intake system
- Visible dirt or damage on your filters
How to change your car air filters yourself?
Changing your car air filters yourself can save you money and time, as well as give you a sense of accomplishment. However, you need to have some basic tools and skills, as well as follow some safety precautions. Here are some steps to guide you:
- Locate your car air filters. You can find them by consulting your owner’s manual or searching online for your vehicle model. The engine air filter is usually in a rectangular box near the front of the engine bay. The cabin air filter is usually behind or near the glove box.
- Remove the old filters. For the engine air filter, you may need to unscrew or unclip the box cover and lift it off. For the cabin air filter, you may need to remove the glove box or some panels to access it.
- Clean the filter housing. Use a vacuum cleaner or a damp cloth to remove any dust or debris from the filter housing.
- Install the new filters. Make sure they fit snugly and securely in their place. Align them with the airflow direction indicated by arrows on the filter or the housing.
- Replace the cover or panels. Screw or clip them back on firmly.
How to get professional help for changing your car air filters?

They have the expertise and equipment to do it quickly and correctly. You can also benefit from their advice on choosing the best type and brand of filters for your vehicle.
