A fresh E82 E90 E91 E92 E93 or X1 cabin air filter (also known as a microfilter or HEPA filter) will allow you to breathe easier, and healthier, by effectively filtering out impurities through your HVAC system. A yearly replacement of your microfilter will ensure dust, pollen, soot, and pollution stay out of your BMW's interior. This cabin air filter uses a multilayer, moisture-resistant filter material with an almost 100% filtration rate. Your microfilter should be replaced once a year or every 15,000 miles. This is a standard paper filter without activated charcoal or carbon.
This is the microfilter for E82 coupe, E88 cabrio, E90 sedan, E91 wagon, E92 coupe, E93 convertible, and E84 X1 SUV.
Regular or Activated Carbon filter? Regular filters are made of paper or textiles that are then electrically charged. The charged filter creates a static surface for foreign particles to cling to. Carbon filters - also known as charcoal filters - also use a textile material but with extra layers of chemically-treated carbon material (literally charcoal or charred wood). The carbon does a better job of trapping and containing foreign particles which makes it a better choice for heavily polluted areas and especially in stop/go traffic. It also does a better job of filtering odors than a standard paper filter. Because of the more complex manufacturing process, activated charcoal filters tend to be more expensive. We offer both paper and activated carbon filters for your BMW whenever available.
