Is my place just especially dusty, or am I just intolerant? If I don't dust at least once a week buildup is visible from across rooms.. Within 2 weeks my computer's temp starts going up because of layers of it, though granted it's on 24/7. Wtf? Is there anything you can do about it short of converting to central air? Do HEPA filters or that Sharper Image thingie (Ionic Breeze?) work? Anything? I'm going nuts here...
