What Does a Cabin Filter Do?

Have you noticed that the air entering your vehicle through the vents is not as strong as it used to be? That might be a sign that the AC filter car needs to be replaced, and it is essential that you do so. While all auto filters help to prevent the influx of harmful debris and particles entering your engine, the cabin filter prevents such debris from entering the vehicle cabin, meaning that this filter assures that you are not breathing in harmful substances. The easiest way to find the appropriate cabin filter for your vehicle is through a VIN lookup, but before you replace this filter, it is necessary to understand if it is the problem.

Aging Filters

Is your A/C system still performing as it should? A dirty cabin filter can equate to a loss of effectiveness in this system. All filters eventually become ineffective as they are intended to capture and contain contaminants. As filters age, it gets harder for air to pass through them, which inevitably leads to inefficient systems and subpar performance.

Benefits of Replacement

While you might now be asking how to replace a cabin air filter, it is beneficial to understand why you should. Replacing an older filter with a new one can improve the performance of reliant systems, like the A/C. However, beyond improving vehicle performance, a cabin filter enhances the air quality of the interior of your vehicle. These filters are designed to trap pollen, mold spores, smoke, soot, dust and smog, meaning that cabin filters help keep your nose and lungs clear of harmful chemicals and debris.

Symptoms of an Old Filter

An old cabin filter can affect the performance of the A/C. However, you might not notice the lull in performance initially. First, you may feel that the blowing force of the vents has diminished considerably. Second, you might sense a reduction in the air quality of your cabin. Perhaps, you will begin sneezing due to increases in pollen and dust. If you notice any of these symptoms, it can signify that it is time to change or clean the filter, depending on your vehicle’s filter type.

Frequency of Replacement

No filter is meant to last forever. Therefore, it is necessary to prepare a maintenance schedule that alerts you to when a filter needs to be replaced or cleaned. In general, air cabin filters should be replaced at least once per year or every 12,000 miles, whichever comes first. However, specific filters have different requirements, as do certain makes and models of vehicles. Therefore, always check your vehicle’s owner’s manual for specifics.

Cabin filters are essential components of your vehicles A/C and air quality systems. These devices ensure that you are breathing clean air while confined to the limited space of your vehicle’s cabin. Therefore, make sure that your filter is properly maintained. When it is time to replace your filter, head on over to your favorite auto parts store, perform a VIN lookup and pick up a new one.
