How do cabin air filters work?

A cabin air filter operates by intercepting and filtering out airborne particles such as dust, pollen, allergens, and other contaminants from the air that enters a vehicle's interior through the ventilation system. Typically located behind the dashboard or glove compartment, the filter is designed with various layers of filtration material, often including activated carbon, to capture and retain these particles. As air is drawn into the HVAC system, it passes through the filter, allowing clean, purified air to flow into the cabin, providing occupants with improved air quality and a more comfortable driving environment. Regular replacement of the cabin air filter ensures that it continues to effectively remove contaminants, contributing to a healthier interior and the optimal performance of the vehicle's ventilation and air conditioning systems.
