CARQUEST provides cabin air filters for all makes and models of passenger vehicles that use this type of filtration device. Here are just a few benefits of replacing your cabin air filter as necessary.
Cabin air filters, also known as passenger compartment filters, interior ventilation filters, pollen filters or dust filters, were initially designed to remove solid contaminants like dust and soot from the air that circulates inside your vehicle. Cabin air filters work to remove nearly 100 percent of airborne particles, like pollen, road dust, soot, and other microscopic particles that decrease the quality of the air being emitted from your vehicle's air vents.
Surrounding vehicles can create an exhaust gas tunnel made up of gaseous odors and pollutants that get funneled right into your vehicle. Unclean air can also lead to allergic reactions, and with over 40 million allergysensitive people in America, the demand for cabin air filters is set to increase dramatically.
Cabin air filters work by filtering the outside air coming into your vehicle. Premium filters are made up of a multi-layer design that traps airborne contaminants that would otherwise be sent into the air you breathe. The first layer uses loosely packed fibers to trap larger, coarse particles. The middle layer consists of fine-spun microfibers. They are electrostatically charged to remove particles as small as 0.3 microns. To put that into perspective, a human hair is between 40 and 70 microns, and the tip of a pen measures about 200 microns. The special pleated design also maximizes the filter surface area leading to the highest possible filtration capacity.
Cabin air filters are typically located under your vehicle's dashboard or attached to the glove box. Others may be located in the engine compartment. In nearly all cases, cabin air filters can be changed in as little as ten minutes.
Since the mid-1980s, automobile manufacturers have recognized the benefits provided by the addition of cabin air filters, and the trend has continued to grow. Cabin air filters are of great benefit to anyone who spends a lot of time in their vehicle - especially those millions of Americans who suffer from hay fever and other allergy-related problems.
Vehicle recommendations may vary, but the general guideline for replacing cabin air filters is every 12,000 to 15,000 miles/20,000 to 25,000 kilometers, or at least once a year. In addition to an unpleasant odor, filters not changed after 20,000 miles or 32,000 kilometers can result in decreased heating and air conditioning performance caused by restricted airflow through the cabin air filter.
