The Mistral filter range is produced by the Campi company, that has since 1992 specialized in the production of cabin air filters, and it also supplies some of the leading names in the After-market sector as well as leading car manufacturers. The Mistral filters are made according to the highest standards in order to ensure a cabin filter of the highest quality. There are two types of Mistral filters: particulate filters and combined filters with activated carbon. All the materials used in the production of Mistral filters are non-toxic and principally consist of nonwoven polyester fabrics. The filtering materials used have been specifically developed for car interior filtering and are clearly free from toxic binding agents and resins. The range of Mistral filters in the particle version covers the majority of the car models in circulation. While the activated carbon combined version is available solely for standard fitted vehicles, otherwise there would be a risk of overloading the ventilation system.
