Another source of interior dust/dirt is the rear exhaust vent on the 4Runner... the flap breaks off and just allows crap in - from right behind the rear driver's side tire!
That won't help with the smoke though. I live a few miles from the fire closest to Los Angeles and it has been pretty bad. The only 'safe' place from the smoke is in the house where we have a good central AC filter.
