Cabin Air Filter: How does it work and why does it need to be replaced?

Air is life… we inhale and exhale air to live. What if it is contaminated? It means you are inhaling toxins. Is it right for your body? No! How to filter the air for healthy ventilation while you are in the car? Luckily your vehicle has a built-in system to filter the air for contaminants. It is your cabin air filter. How does it work? Why do you need to replace it? Let’s discuss this in detail in this blog.

Cabin Filter – How does it work?

To understand the working mechanism of a cabin filter, let’s first talk about the ventilation system of the human body. You inhale air from your nostrils and it travels through your trachea to the lungs bronchi and then from there to the alveoli. Is the air reaching alveoli unfiltered? No, it is filtered air. But where was it filtered? In your nose! There are mucus linings and cilia which filter the dust and other air pollutants. These contaminants are building up in your nose along with the nasal linings and you have to clear the airways for avoiding blockage. Have you noticed the waste you removed from the nasal cavity? It is a solid or semi-solid material of dark yellow or light black color. Now, coming back to the topic, keeping the human ventilation system in mind, think about cabin air filters.

It filters air and is similarly junked up with dirt, rubbish and other contaminants. In this case, the air will not smell fresh. The bad smell is not the only concern, there is much more than that to decide for replacement.

Why replacement is necessary?

Cabin Air Filter installation is an ergonomic approach for the health and safety of passengers. If the installed cabin filter is not working, the air in your cabin is likely to have more harmful and odorous exhaust gases than the air external to the cabin filter. It is because there is much-polluted air on the road due to exhaust gases released by other vehicles including trucks. The gases are filtered and removed before reaching the cabin by cabin air filters. Additionally, they aid in the prevention of pollen and other allergens entering the vehicle.

In addition to the above features, it also helps decrease vehicle maintenance expenses. If there is dirt and polluted air stuck in the cabin, it poses more challenges to the ventilation system of the vehicle. It will make your AC work inefficiently, lowering the horsepower of your vehicle. A dirty cabin air filter might ultimately lead to engine burnout, leading your AC to stop operating if left unattended.

It is suggested that you should replace the cabin air filter after every 30k Miles. However, it’s always a good idea to check your owner’s manual for information on when your air filter should be changed.

Last Words

Cabin Air Filter Replacement regularly is a simple way to keep all of your vehicle’s riders comfortable and your ventilation system running smoothly. A new cabin air filter will not only enhance the quality of the air inside your car, but it will also increase the airflow from the heating and AC system.
