I heard a humidifier will help with most the dust problems, but not all.
On items like my monitor I use a dryer sheet to wipe it down, seems not to get as dusty.
And for other glass items I make up a solution of;
1/4 cup white vinegar
1 tablespoon cornstarch
2 cups warm water
Mix the ingredients in a spray bottle and shake well to dissolve cornstarch. Spray liberally onto glass surface. Wipe dry with a clean cloth or newspapers, buffing to a streak-free shine.
If you live close by where they are doing a lot of construction work, then dust will be more in the place. Or if the walls on the inside are bricks, they might need a surface sealer.
Hope that helps, good luck, :)
