I've always been under the impression that feather dusters simply redistribute dust, but it's a little more complicated than that. Apparently, ostrich-down feather dusters actually work; their feathers will trap the dust, and then you can shake it out later outside of your house. However, dusters made of anything else, including lamb's wool, chicken feathers, or synthetics, won't do a thing to help your home's dust situation. Better to ditch the nonostrich feather duster and opt for some microfiber towels and Method. You can also read some of my other dusting tips here.
