The cabin air filter is located behind the glove box on the passenger side, inside a plastic housing that you access by lowering the glove box.
In the 2014 BMW 328i, the cabin air filter (also called the microfilter) is a single filter in a housing behind the glove box. Replacing it requires dropping the glove box, removing the filter housing cover, swapping in a new filter with correct orientation, and reassembling the glove box. The steps are straightforward but require a little hands-on attention and a flashlight to inspect the space behind the glove box.
Where to find it and how to access
These steps describe how to access the filter and prepare for replacement.
- Open the glove box and remove its contents.
- Gently press in the sides of the glove box to release the dampers and let the box fall down or fully drop, depending on the model year and trim. This exposes the area behind the glove box on the passenger side.
- Locate the rectangular cabin air filter housing. It is secured with a clip or screws in some models.
- Remove the housing cover by releasing the clips or twisting the retaining tabs, revealing the old filter.
- Pull out the old filter, noting the orientation of the arrows indicating airflow from the cabin into the HVAC system.
- Insert the new filter with the arrows pointing toward the HVAC unit; ensure it sits flat and fully seated in the housing.
- Reattach the housing cover, then raise the glove box back into place and secure it.
- Close the glove box and test the HVAC to confirm airflow is normal.
Replacing the cabin air filter helps keep the HVAC system flowing freely and improves air quality, especially in dusty or pollen-heavy environments.

Maintenance notes
As a rule of thumb, replace the cabin air filter every 15,000–20,000 miles, or roughly every 2 years, depending on driving conditions, frequency, and exposure to pollen, dust, or smoke. In heavily polluted or dusty areas, more frequent changes may be necessary.
