Some guy with a microscope says 70% of our indoor household dust is made
up
of human body dander and lint's from our clothes, furniture, etc.... ever
wonder what that other 30% of the dust is made out of.


household dust can be gathered and sent to a laboratory for testing

tests can reveal the presence of fiberglass, lead, etc.

fiberglass in household dust makes the dust look shiny when lit (by sunlight
etc.)

a majority of homes have at least traces of fiberglass
