Innenluftfilter

Innenluftfilter, also known as cabin air filters, are devices designed to clean the air that circulates within the passenger compartment of a vehicle. Their primary function is to remove airborne contaminants before they enter the cabin, thereby improving the quality of the air breathed by occupants. These filters trap a variety of particles, including dust, pollen, soot, and other allergens, which can be particularly beneficial for individuals with respiratory sensitivities or allergies.

The typical Innenluftfilter is installed in the ventilation system of a car, often located behind the dashboard or glove compartment. Over time, these filters become saturated with trapped particles and lose their effectiveness. Regular replacement of the Innenluftfilter is recommended by most vehicle manufacturers to maintain optimal air quality and ensure the proper functioning of the vehicle's climate control system. A clogged filter can restrict airflow, leading to reduced heating and cooling efficiency and potentially causing the HVAC system to work harder.

There are generally two main types of Innenluftfilter: standard and activated carbon (or charcoal) filters. Standard filters are effective at capturing particulate matter. Activated carbon filters offer an additional layer of protection by adsorbing gases and odors, such as exhaust fumes and other unpleasant smells, making them a preferred choice for many drivers. The replacement interval for an Innenluftfilter varies depending on the vehicle model and driving conditions, but it is commonly suggested to be replaced every 15,000 to 30,000 miles or once a year.
