Air Cleaner Element / Air Conditioning Micro-filter

[staffop]

I was looking at the service schedule for the E53 and was trying to work out the difference between the Air Cleaner Element listed as an item to change on the Inspection II vs the Air Conditioning Micro-filter change which is listed on the Oil Service.
One of them I assume is the rectangular shaped filter which slides into a slot under the bonnet. What is the other one?

If I understand what you are asking, they both go under the hood/bonnet. One filters the air for the engine and the micro-filter cleans the air for the cabin.

The micro-filter is located up near the windshield wipers. It is rectangular shaped and come out with the twist of a few brackets. It is located at #4 in the following diagram.
