One day I noticed that you can follow the dust in my bedroom back to the air vent. I took two fresh dryer sheets, stapled them together, and covered the air vent with them using four refrigerator magnets. It catches much of the dust, so now I only dust about once a week or so, depending on how much the central air or heater is running.

I picked up a small "auto duster". The large versions are called "California Car Dusters" and are used to dust the outside of the car in areas where there are water restrictions and car washing isn't allowed at the dollar store.
Go to your local dollar store and buy a hand duster (meant for dusting tables, etc.) Walk to the top of your (non-carpeted) stairs. Holding the railing with your free hand, back down, dusting as you go.
