My approach to dust in the audio room is to let sleeping dogs lie. Vacuum cleaners get dust airborne. I do wipe individual areas. When I do finally vacuum, it's only with the machine cleaned out immediately before and with a high-efficiency filter in it. I also use high-quality filters in the central AC.

I had a high quality filter on the heater and the heater guy who comes to clean it once a year told me to watch the real high end filter as they restrict the air flow too much. Maybe I need a whole house air purifier? What kind of filters do you use noob?
