Mahle Pollen Air Filter (Cabin Filter) - Carbon Activated LAK234 (BMW Z4)

Cabin air filters are very efficient: during only one hour of driving, an air volume of up to 100,000 litres is circulated through the vehicle interior. All the more reason to change cabin air filter elements regularly. MAHLE recommends changing the cabin air filter every 15,000km or a minimum of at least once per year. If the cabin air filter fails or is clogged, the pollutant concentration in the interior of the vehicle can increase to six times of that of the outside air. MAHLE cabin air filters reliably supply the driver and passengers with clean air to breathe, which safeguards their health, well-being and ability of the driver to concentrate even in the event of smog or high pollen count. They also reduce the load on the blower, protect heating and air conditioning from contamination, improve air circulation and prevent dangerous fogging of the windows. In addition, the inside of the windows and fittings remain cleaner for longer.

Cabin air filters with activated carbon elements remove harmful exhaust fumes, dirt and dust as well as high ozone concentrations and unpleasant smells. Their pleat bellows consist of three layers: an activated carbon layer is sandwiched between two layers of non-woven materials. A heat process is used to fuse the filter layers and therefore no solvent containing glues are required. Depending on the vehicle type, activated carbon filters are also available that can be used instead of conventional cabin air filters.
