How to remove and install micro-filter on BMW?

BMW uses a micro-filter to clean the air being passed to the passenger compartment. The unit cleans pollen, dust and other particles from the air to allow better driving comfort. A reduced flow of air from the vents is an indication of a clogged micro-filter.

  1. Open the glove compartment door and remove the inside trim at the heater side.
  2. Remove the glove compartment door straps and the hinge mounting nuts. Remove the door.
  3. Remove the 4 screws holding the cover on the side of the heater unit. Remove the micro-filter from under this cover.
  4. Install the filter, cover and glove compartment door.

Canadian versions not equipped with air conditioning use micro-filters attached to the blower housing. These filters are removed by accessing the blower housing through the engine compartment. The other vehicles have the micro-filter in the heater and air conditioning unit within the vehicle. This procedure covers the internal micro-filter removal and installation.

  1. Place the vents above the glove compartment straight forward and remove from the dashboard.
  2. Remove the 6 screws holding the glove compartment and remove the unit complete with the lower trim panel.
  3. Remove the foot well duct for the heater. Remove the screws holding the control unit bracket and tilt down.
  4. Turn the lock and remove the cover. Pull the filter out of the housing.

To install:

  1. Install the new filter and replace the cover. Turn the cover lock.
  2. Install the control unit holder and the heater duct.
  3. Install the glove compartment, trim and the vents.
