Genuine BMW Cabin Filters

Cabin Air Filters, otherwise known as Microfilters, are used to filter the air coming into the passenger compartment via the circulation and heat/AC systems. It is important to replace your Cabin Air Filter frequently as dirt and dust can build up and prevent it from operating at 100% efficiency. It is recommended to replace the Cabin Air Filter when servicing the vehicle and replacing Spark Plugs, Air Filters, and Wiper Blades.
