For anyone who lives in a city... I'd suggest getting an air filter - any pollen/HEPA filter will do a good job of de-dusting your house. Just a $20 unit from Amazon will do - put it in a hallway and it will get most of your house air as long as you don't keep external windows wide open. As well as keeping your indoor air cleaner, you'll also find that you have to clean dust off surfaces less frequently. I suspect there are big health benefits too, but can't prove that. After a few months, the filter turns from white to dark grey, but I've found it keeps working for even years after that - you would expect it to get full and get blocked, but I guess tiny particles take a real long time to block it.
