Published by Fast Monkey on 3-5-2024

When it comes to car maintenance, certain aspects often go unnoticed. One such component is the internal cab air filter, which car manufacturers have equipped in new vehicles since the 2000s.

In today's blog, we'll explore why it is vital to periodically replace your car's cabin air filter and the benefits it brings. So buckle up, and let's drive on!

Understanding the Cab Air Filter

Although this air filter is small, it's essential to your vehicle's ventilation system. Its primary function is to remove dust, pollen, pollutants, and other airborne particles from the air entering your car's cabin. That ensures the air you and your passengers breathe is clean and free of allergens or harmful substances.

Why Did Car Manufacturers Begin Installing Cabin Air Filters?

Car manufacturers first began installing cabin air filters in response to growing demand and concern about air pollution in urban areas. These air filters became increasingly popular as more people became aware of the importance of breathing clean air.

Improved Air Quality

Regularly changing your car's interior air filter will significantly improve the air quality inside your cabin, especially for people with respiratory conditions or allergies. A clean and well-maintained filter helps to reduce the presence of dust, pollen, and other irritants, creating a healthier and more comfortable breathing environment for everyone on board.

Protecting the HVAC System

Another crucial reason to change your car's cab air filter is to protect the HVAC (Heating, Ventilation, and Air Conditioning) system. A clogged, dirty filter will restrict airflow, making your car's HVAC system work harder to maintain the desired temperature. Over time, that decreased efficiency can also allow dirt, allergens, and smog inside.

Avoiding Unpleasant Odors

Have you noticed a lingering musty smell inside your car? That could indicate that your cab air filter is overdue for a change. A dirty filter can trap moisture, creating a breeding ground for bacteria and mold.

As a result, unpleasant odors can circulate throughout the cabin, making your driving experience far from enjoyable. By maintaining a clean filter, you can eliminate these odors, keeping your car smelling fresh and pleasant.

Where is the Cab Air Filter Located?

The interior air filter of your car is located on the passenger side of the engine, either inside (up above) or behind the glove compartment. Although it's also been known to be located:

  • Under the hood, inside the fresh air intake

  • At the bottom of the dashboard on the passenger side

How Frequently Do You Change the Air Filter?

You should replace the air filter in your vehicle cabin every 12,000 to 30,000 miles. Although replacement recommendations vary from one auto manufacturer to another, so it’s important to check your vehicle owner’s manual. 

Don't Overlook the Significance of the Cabin Air Filter

There's no reason to underestimate the significance of your car's internal cabin air filter. Regularly changing this filter improves the air quality inside your vehicle, protects your HVAC system, and eliminates unpleasant odors.

By prioritizing the maintenance of your vehicle's interior air filter, you ensure a healthier and more comfortable driving experience for you and your passengers. So, the next time you're car is at Fast Monkey Auto, ask if they can replace your car's interior air filter.
