Volvo’s new S80 is the first-ever car model to meet the Swedish Asthma and Allergy Association’s high standards. Clean Zone Interior Package (CZIP) is the name of a new technology that gives clean in-car air and an even more pleasant driving experience.
The air in a car must be perceived to be clean by the occupants, including hypersensitive people. This often requires the ambient air to be cleaned or prevented from entering the car through the ventilation system.
