The cabin (pollen) filter cleans the air that comes into your car through the ventilation system. Replacing it improves airflow and reduces dust, pollen, and odours inside the vehicle.
New cabin/pollen filter (correct for your vehicle)
Screwdriver (sometimes needed)
Torch (optional, helps visibility)
Cabin filters are usually located in one of three places:
Behind the glove box (most common)
Under the dashboard (driver or passenger side)
Under the bonnet near the windscreen (scuttle area)
Check your owner’s manual if unsure.
Depending on location:
Behind glove box (common method):
Open the glove box.
Remove any contents.
Squeeze the sides inward to release stops (on many cars).
Lower the glove box fully.
You should see a plastic cover panel behind it.
Undo clips or screws holding the filter housing cover.
Carefully remove the cover.
Slide the filter out slowly.
Note the direction of airflow (often marked with arrows on the filter or housing).
Be prepared for dust, leaves, or debris.
Wipe out any dust or debris inside the compartment.
Make sure nothing falls into the ventilation system.
Insert the new filter in the same orientation as the old one.
Follow any airflow arrows printed on the filter (very important).
Ensure it sits snugly without bending.
Refit the cover and secure clips or screws.
Return the glove box or panels to their original position.
Start the car.
Turn on the blower fan.
Check airflow strength and ensure no unusual smells or noises.
Replace the cabin filter every 12,000–15,000 miles or once a year.
If you notice weak airflow, bad smells, or foggy windows, the filter may be clogged.
Activated carbon filters help reduce odours and pollution more effectively.
Make sure the car is switched off before starting.
Don’t force panels or clips—they usually release with gentle pressure.
Ensure the filter is installed in the correct airflow direction to avoid reduced performance.
