What can be a consequence of a badly worn cabin air filter?

A badly worn cabin air filter can significantly decrease HVAC (Heating, Ventilation, and Air Conditioning) efficiency. The primary function of the cabin air filter is to trap dust, pollen, and other airborne particles, ensuring that the air entering the vehicle's interior is clean and free of contaminants. When the filter becomes clogged or worn, the airflow into the cabin can be obstructed, leading to reduced air circulation and inadequate temperature control.

Consequently, passengers may experience discomfort due to insufficient heating or cooling, and the HVAC system may struggle to maintain set temperatures. In severe cases, a worn filter can even lead to increased strain on the HVAC system, potentially causing premature wear or failure of components. Therefore, maintaining a clean and functional cabin air filter is essential for optimal HVAC performance.
