in a home about 80% come from us. its usually dead skin and hair that just come off us. sometimes youll notice it floating in a beam of light.

Dust is a general name for minute solid particles with diameters less than 500 micrometers (otherwise, please see sand or granulates and, more generally, finely divided matter). On Earth, dust occurs in the atmosphere from various sources; soil dust lifted up by wind, volcanic eruptions, and pollution are some examples.

dust comes from you. its a build up of your skin molecules. every sec you lose tons of them. its sounds gross when you think about it but you asked about it.
