When was the last time you thought about your car’s cabin air filter? If you’re like most drivers, probably never. But this small, inexpensive part plays a big role in keeping your driving experience comfortable, and even healthy.
Let’s take a closer look at what your cabin air filter does, how often it should be replaced, and the surprising impact it can have on your car’s performance and your well-being.
What Is a Cabin Air Filter?
The cabin air filter is responsible for filtering the air that comes into your car through the heating, ventilation, and air conditioning (HVAC) system. It traps dust, pollen, mould spores, exhaust fumes, and other airborne contaminants before they reach the inside of your vehicle.
In short, it’s what ensures you and your passengers are breathing clean air while you drive.
Why It’s Important
Over time, your cabin air filter becomes clogged with dirt, leaves, and other debris. A dirty filter can:
- Reduce airflow from the A/C and heater
- Make it harder to defog your windows
- Cause unpleasant odours inside the car
- Trigger allergies or breathing issues
- Put strain on the HVAC system, making it work harder and potentially wear out faster
If you’ve noticed your car smelling musty, your windows fogging up more than usual, or weaker airflow through your vents, your air filter could be the culprit.
How Often Should You Replace It?
As a general rule, you should replace your air filter every 15,000 to 30,000 kilometres, or once a year, whichever comes first. However, this can vary depending on:
- Where you drive: Dusty roads, urban pollution, and coastal air (like we get here in Queensland) can clog filters faster.
- Allergy sensitivity: If you or your passengers suffer from allergies or asthma, replacing it more frequently can help.
- Vehicle manufacturer’s recommendation: Always check your logbook or owner’s manual for model-specific guidance.
During your regular service at Auto Leaders, our technicians can check the condition of your filter and replace it if needed.
Can You Replace It Yourself?
While it’s possible to replace a cabin air filter yourself, its location varies by vehicle—some are behind the glovebox, others under the bonnet or dashboard. If you’re unsure or prefer convenience, our team can take care of it during your scheduled car service.
