MINI Genuine Activated Carbon Container Cabin Air Filter

Ridged and narrow, the Genuine MINI micro filter vastly reduces the concentration of contaminants and dirt particles in the car's interior, making the air you breathe inside the car up to eight time purer than the air outside.
Fed through a water-repellent and chemical-resistant plastic polypropylene fleece, the air is filtered by combined mechanical and electrostatic means. Despite its compact external dimensions, the fleece contains a staggering total average of 200,000 square metres in surface area, the equivalent of a 5mm wide strip going right around the Earth.
