Although human skin is a part of dust, dust is actually various things. So what exactly is dust composed of and how is it changing your indoor air quality? The Source There are only two locations that dust can stem from, indoors and outdoors, and we are the culprits that are tracking dust inside from the outdoors. The outdoor part of dust forms from soil particles and pollen tracked in on our shoes or through open doors and windows. This adds up to about two-thirds of the dust in your home. The indoor source of your dust is a number of assorted things. A tiny part of which is, in fact, human skin. Most of it is fibers from your carpet, furniture or bedding, and if you own a pet, there is also some pet dander and fur too.

Dust mites are little arachnids and their primary food source is dead human skin cells and they make up a huge percentage of dust.
