Cabin and Aircon Filters
A cabin filter cleans the air entering the passenger compartment through the ventilation and air conditioning system, trapping dust, pollen and road grime.
What it does
Air drawn in by the blower passes through a pleated element before reaching the vents. Activated carbon versions also absorb odours.
Signs a cabin filter is failing
- Reduced airflow from the vents at all fan speeds
- A musty or stale smell when the fan is switched on
- Windows misting more readily than they used to
- A visibly dirty element on inspection
When to replace them
Roughly annually, and more often on dusty or gravel routes. It is among the most commonly overlooked service items.
What to confirm before ordering
Have these ready and the counter can usually confirm the part in under a minute.
- Element dimensions and the filter location, which is often behind the glovebox
- Standard or activated carbon
- Whether the vehicle has one or two elements
Cabin and Aircon Filters by vehicle
Pick your vehicle for the years and engines covered, and what is specific to that application.
Cabin and Aircon Filters questions
Why does my air conditioning smell musty?
Usually a saturated cabin filter combined with moisture on the evaporator. Replacing the filter is the first step, and treating the evaporator deals with what remains.
Does a blocked cabin filter affect the air conditioning?
Yes. It restricts airflow across the evaporator, which reduces cooling performance and makes the system work harder for the same result.
