In general, if you think that surfaces are becoming dusty, use a cloth and wipe them down with a little soap and water.  Alternatively, there are commercial air fresheners you can buy for your home.

What is the best way to minimize the build up of dust?
user
Try to make sure the fan you use to blow the air in is very efficient, as high efficiency increases the amount of air that is actually moved per second.  Also make sure the filters for the fan are relatively new, and/or clean.
