If you have ever been to one of those quick lube and oil change places, the service technician probably tried to convince you that your cabin air filter needed replacement along with a myriad of other items in the car. While their job is to “upsell” their services, your vehicle’s cabin air filter does need to be replaced in the course of your vehicle’s lifespan.
In this blog, we examine the function of the filter and how to know when it’s time to be replaced.
What is the cabin air filter?
Your vehicle’s cabin air filter functions similarly to the filter(s) you have in your HVAC system at home. Constructed of manufactured material or paper, these pleated filters sit inside your engine compartment behind your dashboard. Where the filter is located may depend on your vehicle’s make and model. Newer vehicles have made them easier to access by opening or removing the glove compartment for access to the filer. It’s best to consult with your owner’s manual for the exact location of your vehicle’s cabin air filter.
What is the function of the filter?
The cabin air filter is designed to block and filter out a variety of contaminants, including outside dirt, dust, smoke, and allergens like pollen. The filter prevents these components from entering the cabin and helps to maintain a fresh and safer air quality inside the vehicle.
How do you know when the filter should be replaced?
Typically, a cabin air filter should be replaced every 15-30K miles driven. That may vary though for drivers in dusty climates, such as the Southwest desert or drivers who tend to drive on dirt roads more frequently. In those cases, it is suggested that the filter be changed at least annually to keep cabin air clean.
What are the common signs of an over-used filter?
Over time, the cabin air filter may become blocked or excessively dirty. A dirty filter will reduce its effectiveness and may even interfere with the function of your vehicle heating and cooling systems.
Some common signs that the filter is ready to be replaced may include:
- Bad smells coming from the air vents when using the air or heat
- A decrease in the air flow from the vents
- Various sounds when using the heating or cooling system such as being louder, or whistling sounds
While a dirty filter may seem like a minor item, neglect of this maintenance item can result in problems within your vehicle.
