BMW Genuine Microfilters are integrated as standard equipment in the fresh air intake area of the air conditioning system. The smallest particles and pollutants are absorbed by the filter. The benefits of this can be seen when driving in heavy city traffic, tunnels or in traffic jams where high concentrations of dust and pollutants can become unpleasantly noticeable.
A BMW Genuine microfilter is matched to the ventilation system so that filter performance and air quality remain unaffected for as long as possible with low noise operation.
BMW Service Authorised Workshops only use BMW Genuine Microfilters.
