Air-matic filter replacement




On my 220D 4matic is time for service maintenance and i won't do it in dealer as my guarantee expired and i see no reason to go there for simple change of oil and filters. My question is, how often you change filter of the air-matic system? I have MANN filter for 10$ and it can be done about 20 min with right tools and place. So my car is on 50 000 km and 2 and half years and i'm considering to change this filter too.
