BMW and MINI DIY Video – Replacing The Cabin Microfilter (Micro Filter) How To

November 15, 2010

Most BMW and MINI owners are very good about changing their engine’s air filter, but they rarely change the cabin air microfilter. (If your response is, “I didn’t even know my BMW had a cabin air microfilter,” you’re not alone.)  The size and shape of these filters vary widely from model to model, as does the step-by-step procedure for changing them.

Dirty filter on top, clean filter below

BMW and MINI recommend that these filters be changed every 15,000 miles (down from 30,000 originally).  Otto recommends once per year or more often if the vehicle is used in “dirty air” areas.  A 6-month inspection of the filter will reveal where the actual change interval should be.  Once you install the new microfilter, you’ll notice that the car smells fresher and the AC works better.  Bavarian Autosport stocks all of the BMW and MINI micro-filters at or call our agents at 800-535-2002 for assistance.

    Is this a similar process for my 2003 325xi?

  3. How about a similar video for us 3-Series owners?

    • What year is your 3-series? See the prior reply for the E46 models (3-series 99-05)

  4. will you put up a video to change the cabin filter for the ’07 Z4?

    Excellent. Got a video on an E90 325XI Sedan?

  6. steve permalink

    Do you have instructions for my 2001 525i?

  7. bartlett permalink

    What about the 3 series?

  8. Does the E-30 have this filter? Mine is a 92 318iC.

    • The E30 models (3-series 84-91 .. plus 92 convertible) do not have micro-filters.
