Having your air/heat ducts professionally cleaned will cut atleast 50% of the dust from your home,addiny a layer of cheese cloth to the back of each register helps a ton too.
The attic is another dust trap,if you have insulation in your attic you can lift out the insulation,vaccume & clean between the joists & install a layer of plastic sheeting,tape all the seams in the plastic with duct tape & re lay all the insulation.
I know it seems like alot of work & it is but doing these things will make a massive difference in the dust in your home & on your gear & dosent cost much except your time.
