Even though we don't live near new construction we still get a lot of dust. One of the first things I did after moving here was replace the furnace filter with a filter in the return air vent. I bought the necessary material at either Home Depot or Lowes (it was eight years ago). It doesn't solve the dust problem but it prevents a build up of dust in the duct work.
My HVAC people said they tried to get the builder to include return air vent filters as standard but they couldn't convince him.
I have also replaced carpet in all but 2 guest rooms with hard floors.
Having done all of that I would like to say problem solved. It helped but we still get a lot of dust.
