BMW Cabin Air Filters, Heppa Filters, & Microfilters for BMW 5 Series E39 (1996-2003)

Clear BMW chassis

Breathe fresh air again! As an important part of your car's heating ventilation and air conditioning (HVAC) system, the microfilter should be replaced every year or 10,000 miles. If the microfilter (cabin air filter) becomes clogged it can reduce the blower output and lead to odoriferous emissions.
