Filter, cabin air

The Filter, cabin air (AHH378) cleans incoming air to improve cabin comfort and HVAC performance. Replacing the filter ensures fresh air and optimal ventilation. Use Porza’s smart search to find the correct filter.

FAQ

A cabin air filter is a component in the vehicle’s ventilation system that filters the air entering the interior. Its function is to remove dust, pollen, pollutants, and other airborne particles, ensuring clean and healthy air inside the cabin while improving comfort for passengers.

Key specifications include filter dimensions, filtration efficiency, and filter type (standard particulate or activated carbon). Activated carbon filters provide additional protection by absorbing odors and harmful gases. The filter media is typically made from multi-layer paper or synthetic materials designed to maintain airflow and operate within temperature ranges from -20°C to +80°C.

Replacement is recommended at regular service intervals, usually once or twice per year, or when symptoms such as reduced airflow, unpleasant odors, or increased dust inside the cabin occur. More frequent replacement may be needed in urban or polluted environments.

Porza offers a fit guarantee option where your vehicle details, such as license plate or VIN, are checked against product specifications. This ensures the cabin air filter matches the correct size, type, and performance requirements for your vehicle’s HVAC system.

Porza supplies high-quality cabin air filters with fast delivery across Europe. Customers can order online or choose in-store pickup in the Netherlands, Germany, or Belgium. This allows quick and flexible access to essential maintenance parts for both professional workshops and individual users.

If you select the fit guarantee, Porza verifies compatibility before shipment. If the product does not fit or meet expectations, it can be returned according to the return policy. This ensures a reliable and risk-free purchasing experience.
