On my trip when passing road trains etc and having to stop in the massive cloud of dust or when following too close in a dust cloud I never had a problem with dust with the A/C on auto. I expect the pollen filter will be very dusty though. I just had my car serviced and the pollen filter was changed for the first time since the trip in September. I haven't noticed any difference since changing it, however.

Pretty much the same as most have said! I have the intake air on fresh direct from the outside via the filter and the fan on a postion about mid way on the dial or above so that I am creating a positive pressure inside the vehicle. This ensures no dust ingress through any gaps in the seals etc. I must say I have not detected any gaps. I also use recirculate if I get into close proximity to other vehicles or for passing traffic that may be generating a dust cloud.

Note: Once activated the recirculate automatically goes back to fresh after a set period. Not sure if that aspect is adjustable?

The net result is a clean and dust free (as much as is possible on my local dirt roads) interior.
