Does common household dust really contain 80% human skin?

I once heard this before and was shocked but never knew what to think of it, please does anyone have any insight?

Does common household dust really contain 80% human skin?
I read a lot about dust on the www because my son's allergic to dust mites. I've heard that human skin composes a high % of dust, but I can't track down the source of this. It sounds gross, but that's how dust mites live-- they eat our dead skin cells. A vacuum cleaner salesman once told me that dust is "DEAD THINGS." He said this in a very creepy tone that made me run out of the store as fast as I could!





oh, here's a website about a guy who likes to look at dust under the microscope... and he stains the dust so he can tell the difference between organic and non-living material. fascinating stuff. who would have known dust could be so complex!

Reply:yes because your skin comes off as you move and most people are inside a lot.
