Audi A4 Cabin Air Filter

Audi A4 Cabin Air Filter is developed to protect all occupants against dust, pollen and exhaust fumes by cleaning the air that comes into the HVAC vents. It is placed in the outside air intake of the passenger compartment and is available in a pleated paper media or a reusable mesh barrier, which prevents the odor of stale air and does not require the blower motors to work extra hours. During the manufacture of its models, Audi mainly uses disposable pleated parts in the shape of a flat rectangle or in the shape of the cowl, which can be washed and reused, and in the history of automobiles there is also a washable aluminum-framed version that can be removed, cleaned and reinstalled. The paper version provides greater filtration efficiency for small particles, whereas the reusable unit is resource-saving but eliminates fewer microscopic allergens, which is why filtration quality is the major difference between the two designs. Audi suggests replacing the Cabin Air Filter at the frequency mentioned in the owner's manual and changing the filter earlier if the vehicle is frequently driven on dusty back roads or in traffic where soot forms easily. When this service is ignored, the element becomes clogged, choking the airflow and overworking the HVAC fans, even to the point of making the cabin of an Audi stinky in humid weather. When the vent output is diminished or when unusual odors occur, a new Cabin Air Filter restores a clean flow and assists the system in your A4 in operating soundly and efficiently. The Cabin Air Filter enhances all drives in an Audi; with basic installation and essential protection, it makes every ride in the car a little healthier and more comfortable.
