What is a cabin air filter and how does it work?

A cabin air filter is a component of the climate control system in your vehicle. The filter prevents dust, pollen, and other debris from entering the passenger compartment through the heating and air conditioning components. This is similar to the way a furnace filter works inside your home. The filter also helps to remove foul odors that might enter the cabin space. The cabin air filter is typically made of paper or foam suspended in a plastic frame. Some filters contain activated carbon to eliminate fumes. The cabin air filter is inserted into the ductwork inside your vehicle, in the path of the airflow from the vents. That way, whether the air is coming from outside the vehicle or is being recirculated, it passes through the filter.

What are signs that a cabin air filter needs to be replaced?

Your cabin air filter is at work during all seasons and across a wide range of driving conditions. It collects dust, sand, pollen, and other contaminants so that they do not enter the passenger compartment through the vents, and so that you do not have to breathe them. Other debris also tends to collect in the filter. For instance, if you park under a tree, leaves, seeds, and small twigs can enter the external vents and end up inside the cabin air filter compartment. Odd odors that pass through the filter can become trapped as well, causing it to smell inside your vehicle. If you notice that the airflow from the vents has decreased, or the smell coming from the vents becomes musty, moldy, or otherwise foul, it is probably time to replace your cabin air filter.

How is this service performed

How is a Cabin Air Filter Replacement done?

Changing a cabin air filter requires a similar procedure to be followed for most vehicles. The service is fairly straightforward, since access to the filter is generally in the same location - underneath the dashboard ahead of the glove box on the passenger side of the compartment. That said, there are slight nuances from one vehicle to the next, such as how the glove box door is removed, how the filter housing is opened, or how deep the housing is set into the dashboard. To change the filter, a mechanic will perform the following basic steps

  • Open and empty the glove box compartment
  • Detach the glove box door check strap or mechanism
  • Swing the glove box door down and out of the way or remove the door completely
  • Locate the filter housing and remove the housing cover
  • Withdraw and discard the old filter
  • Insert the new filter, taking care to note its proper orientation with the airflow
  • Replace the housing cover, reinstall the glove box door and strap

OTHER QUESTIONS CUSTOMERS ASK

What happens if you don't replace your cabin air filter?
In time, a cabin air filter will become embedded with dirt and debris. If you tend to drive in dusty conditions or park under trees, it will clog sooner. When it does, the function of your heating and air conditioning system will become compromised, and foul odors will build up.
Can I change my own cabin air filter?
Most cabin air filters can be changed with relative ease in about fifteen minutes with few or no tools. That is not to say that all cabin air filters are easy to replace. Some are more difficult to access than others. On the other hand, a trained technician can perform the service quickly while taking care of other routine maintenance items at the same time.
Is it okay to drive without a cabin air filter?
There is no direct impact on the overall performance of your vehicle if your cabin air filter is either dirty or missing. On the other hand, if it becomes significantly clogged, airflow from the vents will be affected. If no filter is present when the vent fan is on, the outside air - and all of the dust, pollen, and other debris it holds - will enter the cabin. Dust will collect on interior surfaces. More importantly, you and your passengers will breathe the allergens and contaminants.
