1. Article provided by wikiHow, a wiki how-to manual.

   Steps

   1. 1
      Get the filters from an auto parts store. This particular model takes TWO filters, so remind the auto parts guy you need two.

      
      
2. 2
   Open hood and find the two plastic covers, one on each side just in front of the windshield.
3. 3
   Open the clip on the inner side of each cover. It will pop out from the front. Slide it off of the hinges in back to pull the cover out and flip it over.
4. 4
   Remove the old filter, then blow out all the debris in the housing so it doesn't end up going through the interior vent.
5. 5
   Place the new filters in the housing and replace the covers.
6. 6
   Reset the Service Reminder (see How to Reset the Service Reminder for 2006 BMW 525xi).
