Step 1: Locate the Cabin Air Filter
Locating this component in your four-wheeler is the first step in replacing it. The location can vary depending on the make and model of your car, but it is typically located in the HVAC system under the dashboard on the passenger side of the vehicle. In some cases, the filter may be easily accessible from under the hood or behind the glove compartment, while in other cases, it may require removing a cover or panel to access it. Here are some common locations:
Under the Dashboard
Many cars have these filters located under the dashboard on the passenger side. It can be accessed by opening the glove compartment and removing any stops or screws that hold the compartment in place. It is usually located behind a cover or panel that can be removed by unclipping or unscrewing it.

Some vehicles have them located behind the glove compartment. To access them, you may need to remove the glove compartment by releasing any retaining clips or screws that hold them in place. Check also for housing that can be opened or removed to access the filters.
Under the Hood
Some four-wheelers have these components located under the hood, near the windshield wipers or firewall. They can be accessed by lifting the hood and locating the housing that holds the filter.
Step 2: Remove the Old Cabin Air Filter
The next step is to remove the old element. Once you have located the housing, open it up and carefully remove the old filter. Depending on the type of housing, filters may be held in place with clips, screws, or a latch.

Step 3: Clean the Air Filter Housing
It’s important to ensure the housing is completely ready for a new part you’re planning to install. That way, the new filter will work effectively and provide clean air to the cabin. After all, don’t expect that only the filter gets dirty over time.
Dirt and debris can accumulate in the filter housing, which can hinder airflow and reduce the efficiency of the HVAC system. Cleaning the housing will help remove any contaminants and ensure proper airflow.
How to Clean the Air Filter Housing Effectively?
To clean the air housing effectively, first, remove any loose debris or dust using a soft cloth or a vacuum cleaner. Then, use a damp cloth or a mild cleaning solution to wipe down the interior of the housing, being careful not to damage any components or the housing itself.
Make sure to remove any dirt or debris that may have accumulated in hard-to-reach areas, such as corners or crevices. Allow the housing to dry completely before installing the part. Cleaning the housing thoroughly will help to ensure proper airflow and improve the efficiency of the HVAC system, which will, in turn, provide cleaner and healthier air to the vehicle’s cabin.
Step 4: Install the New Cabin Air Filter
Before you begin, it’s important to select the right replacement cabin air filter for your vehicle. These filters come in various sizes and shapes, so it’s important to choose one that matches your car’s make and model. To select the right replacement, refer to your car’s owner’s manual or consult with a parts specialist at an auto parts store. They can help you find the right fit for your car.

- Close the housing – Carefully close the housing, ensuring that any clips or latches are securely fastened.
Step 5: Test the New Cabin Air Filter
To test the new part you just installed, turn on the heating, ventilation, and air conditioning (HVAC) system and set it to the highest fan speed. Take note of the airflow from the vents and any unusual smells or sounds.
If you notice any issues, such as reduced airflow or strange smells, double-check the installation to ensure it is properly secured and inserted in the right direction. If the issue persists, it may indicate a problem with the HVAC system, and it may be necessary to seek the assistance of a professional mechanic.
If everything seems to be working correctly, take note of the improved air quality in the car’s cabin. The air should smell cleaner and fresher, and any dust or debris that was previously present should be gone.
