The outdoor part of dust consists of soil particles and pollen tracked in on our shoes or through open doors and windows. This contributes to about two-thirds of the dust in your home. The indoor source of your dust is a number of assorted things. A little part of which is, in fact, human skin. Most of it is fibers from your carpet, furniture or bedding, and if you have a pet, there is also some pet dander and fur also.
