Two suggestions. First, a decent air purifier will cut a significant portion of particulate keep the air moving so it can't settle. Second, some overwhelming >90% of dust is human skin cells. Wash your body and scalp every day, and try to spend less time in one location, esp with closed doors. I'm not gaffing on you - your house doesn't generate the dust - you do. Cut it at the source, filter your air, and you will see a huge improvement. Active cleaning is only worth pursuing once you've addressed the first two, otherwise you're just busting your ass without fixing anything. If you filter your air and wash yourself you should only have to lightly blast canned air once a month and the filter will grab whatever trivial amount you put up in the air.
