Cabin Air Filter Service: Everything you need to know
Have you noticed a musty odor in your car lately? Or is your car’s heat and air conditioning not working as they usually do?
This all may be happening because of a clogged air cabin filter. Clogged filters can impact the flow of air which your vehicle HVAC system depends on. A dirty cabin air filter can reduce airflow through the vehicle’s heating and air-conditioning system, contribute to unpleasant odors, and allow more dust and allergens into the cabin.
So, what is a Cabin Air Filter, and how does it work?
The cabin air filter is a small size pleated filter. It’s usually made of multi-fibre paper cotton that cleans the air that comes into the interior through the heating, ventilation and air-conditioning system. It catches dust, dirt, debris and other airborne material such as pollen that can make your ride unpleasant.
When the windows of your vehicle are closed, air enters the cabin through the ventilation system. The ventilation system supplies air to the heater and air conditioner, but before it reaches the heating and AC system, it also has to pass through the cabin air filter.
As the air passes its way to the cabin, particles like dust, smoke, pollen, and larger debris like leaves get trapped into it. Thus the air that ventilates the cabin is kept clean and fresh for you.
Over time, the filter will collect too much dust, debris and/or particles, so the point it can no longer collect any. When this happens, whatever is missed is passed through the filter and ends up in the cabin space with vehicle passengers.
It is important to regularly have your filter inspected and changed when needed to prevent this from happening.
How do you know if cabin air filters need changing?
As mentioned above, cabin air filters no longer serve their purpose if they fill up with harmful contaminants. Some warning signs will let you know that your cabin air filter may need replacement. These signs include:
- An unusual odor from cabin – Dirty filters often lead to the growth of bacteria or mold. If you notice a foul smell inside the car even when the cabin is clean, then it may be time to replace your cabin air filters.
- Windows that fog up more easily – A restricted cabin air filter can reduce airflow through the defrost system, making it harder to clear condensation from the windshield and windows.
- Reduced air circulation -If you find that you are cranking up the AC higher than usual, it is because the cabin air filter could be clogged with dirt. As a result, it restricts the amount of air entering into the cabin.
- Increased fan noise – When large materials enter the cabin air filters, there is an increase in the fan’s noise, and when you increase the flow of air, you notice high noise coming from the AC blower. In this case, you have to replace your dirty cabin air filters with a new ones.

- Cleaner cabin air – A new cabin air filter helps reduce dust, pollen, road debris, and other airborne contaminants entering the passenger compartment.
- Reduced exposure to airborne contaminants – A clean cabin air filter can help limit the amount of dust, pollen, soot, and other particles entering the vehicle’s interior.

How often should you change your Cabin air filter?
Each vehicle manufacturer has its recommendation on when to change the cabin air filter that can be found in the owner’s manual.
Generally, it is recommended to replace it between 20,000 km to 30,000 km.
That being said, your driving habits and conditions can play a large role in when your air filter may need to be replaced. For example, if you live in a rural community and travel a lot of dirt or gravel roads, your air filter will get dirtier quicker.
