Most dust inside your house is dead skin. Dust gets blown around your house by your heater, fans, walking around and stirring it up, etc. If you open your windows in the summer, you'll get a lot of dirt particles coming in the house that way. Lint from your clothes. Pets. The list goes on and on.

Over a 6 month period, your body replaces 90% of its molecules (the remaining 10% are things like neurons in the nervous system). This mass must go somewhere-a high proportion is lost as faeces, but a lot (inc. dead skin) is simply 'shed' off into the surrounding environment.
The reason that it gets into all these places we haven't touched for years is simply that air is never still. It is constantly moving due to changes in pressure, temperature and movement. The dust particles are carried in the air and lie everywhere. They simply sit in the places we don't touch for that reason-there is nothing to clean them off or wipe them away.
This is true for everything-look at anywhere that dust can feasibly lie (ie not a vertical wall or ceiling) and where it is not constantly touched or cleaned, and indeed there you will find dust.
Hope this helps :)

Dust is made when any material gets abraded from rubbing on another object of the same or different material. Very little of the dust you encounter, even in your home, is dead skin cells. Dust builds up in areas of "stagnant" air where it is not disturbed. The air in a room is rarely truly stagnant, but it moves slowly enough that dust particles carried into a room precipitate out. "Fresh" air coming into the room brings more dust with it.

Object lessons abound throughout creation, and they are for our learning. Here is a question I have asked earlier, some food for thought What proofs do we have that Adam and Eve existed? 1.Jesus believed they existed. 2. The New Testament writers believed they existed. 3.They were made from earth materials and we need minerals in our diet to keep fit. 4. I don't believe evolution can produce a male and a female at the same time that fit together so perfectly physically, mentally, and emotionally. 5.Women have pain during childbirth. Part of the curse.

Those before me have covered it to the point of...Sheesh!
All that's left is for me to go on record that I'm not in favor of dust and it wouldn't hurt my feelings a bit if I never breathed another lungful of the stuff. I gave up smoking but I just can't shake the dust habit. Woe is me.

because air circulating around the room from the ac or vent mixes with skin cells that naturally slough off...it is then carried to places you don't normally bother or touch and it accumulates.
