Your cabin air filter is the only barrier between the outside air and what you and your passengers are breathing inside the vehicle.
It traps dust, pollen, bacteria, mould spores and exhaust particles from other vehicles on the road before they enter the cabin.
When it blocks up or degrades, that protection disappears, and every trip becomes a lungful of whatever is in the air around you or what is growing in your filter.
At WestCoast Auto Air Conditioning Mandurah, we supply and fit replacement cabin air filters on most makes and models — no booking required for most vehicles.

When Should You Replace Your Cabin Air Filter?
Most manufacturers recommend replacing your cabin air filter every 15,000–20,000km or once a year, whichever comes first.
Signs it needs replacing sooner include:
- Reduced airflow through the vents even on high fan speed
- Musty or stale smells when the AC or heater is running
- Increased dust inside the cabin
- Allergy symptoms worsening while driving
