Product Overview

The cabin air filter, OEM number 64119237555, is an activated charcoal filter fitted to the BMW F30/F31/F34 3 Series and F32/F33/F36 4 Series, covering the 2012-2021 production run. Since this filter spans two of BMW's highest-volume sedan and coupe platforms, it's a high-turnover part number worth stocking in significant volume for distributors serving BMW cabin filter parts demand.

A worn or clogged cabin filter typically shows up as reduced airflow from the vents, musty or unpleasant odors inside the cabin, or increased dust and allergens reaching the driver and passengers. GSK Auto manufactures this cabin air filter to OEM specification at our Ningbo, China facility, with every unit tested before packing. We supply at wholesale volume with low MOQ and support private label packaging, with our team available to confirm fitment before shipping.

What Is a Cabin Air Filter?

Function: The cabin air filter cleans the air entering the passenger compartment through the HVAC system, trapping dust, pollen, and other airborne particles before they reach the driver and passengers.

Working Principle: Air passing into the cabin ventilation system flows through the pleated filter media. The activated charcoal layer additionally adsorbs odors and certain gases, providing a further layer of filtration beyond particulate capture alone.

Importance: On BMW's high-volume 3 and 4 Series platform, a properly functioning cabin filter is essential for driver comfort and clean cabin air quality.

Common Failures & Signs: Reduced airflow from the cabin vents. Musty or unpleasant odors from the HVAC system. Increased dust or allergens noticeable inside the cabin. Noisy blower motor as it works harder against a clogged filter.
