Where Does Household Dust Come From?

This is an age old question. Actually household dust comes from many sources. Dead skin cells is one source, but contrary to myth, it isn’t the main source. About 60% comes from outside (through clothes and air). Other sources are carpetting and upholstery, pet dander, food crumbs, and a host of other things.  https://molekule.science/where-doest-dust-come-from-source-house-solutions/
