My living room items get very dusty due to my windows always being open. I have wooden ships and knick knacks. I use compressed air in the can (the same kind I use on my laptop keyboard) to spray the dust off of them.
This is a great idea, however, these cans of air are not cheap, and this could be costly. Just my thought...
This doesn't get rid of the dust; it just moves it around and if you have allergies not such a good idea.
