In every car, there is a cabin air filter. It is different from the engine air filter, which cleans the air for the engine. Instead, the cabin air filter purifies the air that flows through the heating, ventilation, and air conditioning systems. The cabin air filter is easy to forget about and is often overlooked, but it’s usually inspected during an oil change. This makes it a convenient time to think about if it’s due for a replacement.
The Role a Cabin Air Filter Plays In Your Car
Just like any air filter, the cabin air filter works by capturing dust, pollen, smog, and other harmful or irritating particles from the air that flows through it. It acts as a barrier between you and the outside environment while driving, ensuring that you and your passengers breathe cleaner, healthier air inside your car.
Issues That Occur From Not Changing Your Cabin Air Filter
Not changing your cabin air filter when you should creates a few noticeable issues:
Odor
As the cabin air filter traps dust, dirt, and other particles from outside, it can get clogged over time, leading to unpleasant odors. If mold and mildew start growing in the filter, they can also lead to bad smells.
Fog Build-up on Windows
An old and clogged cabin air filter will lead to poor air circulation. This can cause condensation to form on your windshield and other windows, which is particularly dangerous when driving in rainy or foggy conditions.
Whistling Sound and Other Noises
When a cabin air filter needs changing, it tends to create a whistling sound from the cabin air intake ducts. You may also notice other types of sounds occurring when you run the heating or cooling system.
Your Health Is At Risk
A dirty cabin air filter collects moisture, and you know what loves moist places? Mold and mildew. Gross, right? Besides causing foul odor as mentioned earlier, an unclean cabin air filter with mold and mildew can make you sick. Plus, since the filter can’t trap more particles like dust and pollen, you end up breathing unfiltered air in your car, which can worsen allergies and respiratory problems.
Where Is My Cabin Air Filter Located?
So, it’s clear you should replace your cabin air filter, but where do you find it? Commonly, a cabin air filter is found behind the glove compartment, but they can also be found in other areas, too, like under the hood or behind the dashboard.

Behind the Glove Compartment
If you need to access the filter behind the glove compartment, you’ll usually start by taking off a small panel from the back of the compartment. Sometimes, though, you might have to remove the entire glove compartment. Then, you’ll be able to access the filter housing and replace the filter.
Under the Hood
In older vehicles, you will often find the cabin air filter under the hood. To access it, start by lifting the hood of your vehicle. Look for the cowl area, which is the space between the windshield and the hood. This is where the cabin air filter will be found. Next, carefully remove the cowl panel or cover that protects the filter. After removing the panel or cover, you will have direct access to the cabin air filter.
Behind the Dashboard
Finding the cabin air filter behind the dashboard is a less common area, and accessing it can be a bit tricky depending on your vehicle. In some cars, you might get lucky and reach the cabin air filter without taking apart any trim or dash panels. However, for others, it’s a bit more complicated and requires you to remove these parts. Refer to your car’s manual or consult with a professional if you’re not comfortable tackling this task.
