Step 1: Confirm the correct cabin air filter

Before starting your DIY cabin air filter replacement, verify the correct filter for your year, make, and model.

1. Look up the part number in your owner’s manual or on a parts retailer’s website.

2. Confirm whether your vehicle uses a standard cabin air filter or an upgraded charcoal/activated carbon cabin air filter for better odor and pollutant control.

3. Compare the new filter’s size and shape with the old one once removed to ensure a proper fit.

Step 2: Locate the cabin air filter

Most vehicles position the cabin air filter in one of three places:

• Behind the glove box

• Under the dashboard on the passenger side

• Under the hood near the base of the windshield (cowl area)

Check your owner’s manual under “cabin air filter,” “pollen filter,” or “HVAC filter” to confirm the exact location and access method. 

Step 3: Access the cabin air filter housing

The most common setup is behind the glove box. In many vehicles, you will:

1. Open the glove box and remove its contents.

2. Release the glove box stops by gently squeezing the sides inward or removing a small damper arm or screw, so the glove box can swing down or be removed.

3. Look behind the glove box for a rectangular cover or door that houses the cabin air filter.

If your vehicle’s cabin air filter is under the hood or under the dash, you will typically remove a small plastic panel or cover to reach the filter.

Step 4: Remove the old cabin air filter

Once you can see the filter housing:

1. Release any clips or tabs holding the cabin air filter cover in place.

2. Carefully slide the old cabin air filter out, keeping it level to avoid spilling dust, leaves, or debris into the HVAC system.

3. Note the orientation arrows indicating airflow direction on the old filter, as you will need to match this when installing the new filter.

At this stage you can take a photo for reference if you are new to DIY cabin air filter replacement. 

Step 5: Clean the cabin air filter housing

Before installing the new filter:

1. Inspect the filter compartment for leaves, dust, or other debris.

2. Use a small vacuum to remove loose dirt from the housing if needed.

3. Wipe the area with a clean, dry cloth if there is light residue or dust buildup.

Cleaning the housing helps your new cabin air filter last longer and supports better airflow through the HVAC system.

Step 6: Install the new cabin air filter

Now you are ready to install the replacement cabin air filter.

1. Compare the old and new filters to confirm they are the same size and style.

2. Locate the airflow direction arrows on the new filter (often marked “AIR FLOW” with an arrow).

3. Insert the new cabin air filter into the housing with the arrows pointing in the same direction as the old filter.

4. Make sure the filter sits flat and fully seated in the housing, with no gaps or bends.

5. Reinstall the filter cover or door and secure any clips or tabs.

Step 7: Reassemble the glove box or panels

Once the new cabin air filter is installed:

1. Lift the glove box back into position if it was removed or lowered.

2. Reattach any damper arm, screws, or side stops you disconnected.

3. Return your belongings to the glove box.

4. If the filter was accessed under the hood or under the dash, reinstall any covers or panels removed earlier.

Turn on your vehicle’s fan to confirm proper airflow and check for unusual noises or obstructions.
