Cabin Air Filter

The BMW Genuine Parts 64119237159 is a recirculated air cabin filter, also known as a microfilter, engineered to enhance the air quality within your BMW's interior. This filter effectively traps dust, pollen, soot, and pollutants, contributing to a healthier environment inside your vehicle. It is recommended to replace this filter once a year or every 15,000 miles to ensure optimal performance of your HVAC system and consistent air purity. This is distinct from a fresh air filter. The X3/X4 models equipped with automatic climate control have a separate set of filters for the recirculated air system, and this product includes both panels for that system. Constructed by an OEM supplier to BMW and other European manufacturers, this filter utilizes a multilayer, moisture-resistant filter material that boasts an almost 100% filtration rate. Unlike standard paper filters that use an electrically charged surface, activated charcoal filters, like some alternatives, incorporate additional layers of chemically-treated carbon material. This carbon layer enhances the trapping of foreign particles and is particularly effective at filtering odors, making it a superior choice for areas with heavy pollution or for frequent stop-and-go traffic. While activated charcoal filters may offer enhanced odor filtration, this particular model focuses on high-efficiency particle filtration for recirculated air. This cabin air filter is compatible with BMW X3 Series F25 models from 2011 to 2017, including the sDrive28i, xDrive28d Diesel, xDrive28i, and xDrive35i. It is also compatible with BMW X4 Series F26 models from 2015 to 2018, including the xDrive 28i, xDrive 35i, and M40i xDrive.
