We wipe it off. We sweep it. We vacuum it. Still, it comes back. But have you ever wondered where they come from? Of course it’s obvious that the dust comes from the outside. It can be from your open windows, or from your shoes, or from your clothes. But did you know that only two-thirds of dust come from the outside? If that is the case, then where does the remaining one-third come from?
It turns out that dust can be generated inside your home as well. And you are also a part of making them.
How does dust affect our health?

I thought a lot came from dead skin cells that sloughs off our bodies. Used to like illustrating dust in the air when I was teaching biology. I'd use the bright light from my overhead projector to show the Tindall effect with the dust in my classroom air.
