Air filters and cabin air filters are essentially the same; they both purify dirty air and allow only fresh air to enter. Air filters protect engine components from wear and tear, while cabin air filters block allergens and airborne contaminants from entering the cabin interior, thus improving cabin air quality. The cabin air filter is located in the duct system to filter pollen and dust particles that enter a vehicle through its heating, air conditioning, and defrost systems. It is visually similar to engine air filters and is sized based on the volume of air that needs to be filtered for efficient operation.
An air filter ensures that no dust particles enter the car's engine, while the cabin filter filters air entering the car's cabin through the HVAC system, heating, and ventilation. It traps dust, pollen, and other airborne materials that can make driving in a car unpleasant, especially if you have allergies or other respiratory problems. Air filters not only prevent engine inefficiency by maintaining air quality, but they also increase fuel consumption, horsepower, and torque. Cabin air filters are typically located behind the glove box, under the dash and under the hood, while some vehicles have the air filter installed inside the HVAC housing between the fan motor and the evaporator core. Increasing pressure drop from air moving through a clogged filter could reduce fresh air supply to the passenger compartment of vehicles and cause the fan motor to work harder to overcome the restriction.
Changing the cabin air filter is essential to preserve the efficiency of your car's HVAC system and to prevent dirt and debris from clogging the filter. In terms of filtering efficiency, once the filter becomes clogged with debris, its ability to capture smaller and more likely more harmful to health particles is reduced. The best time to do this is when you perform the annual replacement of your cabin air filter, saving you time and effort accessing this part of the system. These are literally systems that have replaceable scent cartridges that allow the driver to choose a fragrance to add to the cabin air for a new individualized in-car air quality experience.
