Put away the feather duster. Microfiber dusters or electrostatic dusters actually collect the dust. A feather duster “simply spreads dust from one surface to another.”
Use moisture. Dust becomes airborne easily when it’s dry, so spritz your microfiber duster or cloth with a dusting spray or polish before you use it. Don’t spray polish directly on furniture because you’ll create a buildup.
Don’t neglect vents. The grills on your heating and air-conditioning vents are “hidden dust magnets”; if you don’t regularly vacuum or otherwise clean them, the air blowing through them will spread dust throughout your rooms.
Change your vacuum filters. Speaking of vacuums, remember to clean or replace your machine’s filter as often as the manufacturer recommends. Your vacuum should help reduce dust, not spew dust into the air.
