Would an airtight room still collect dust?

Question

I've read that 70% or so of all dust is dead skin (ewww), which must be carried around by air currents. I know that when I have closed a room off for summer/winter, dust collects.

But if that room were airtight, and those air currents unable to enter, would the room still collect dust? Less dust? No dust?

Just one of the strange thoughts that occurred to me in the shower this morning . . . :o}

Answer 1

during the construction of the room you'd have to ensure that no air trapped inside had dust in it. which is practically impossible. i guess if you rigged up a sort of vaccuum pump to the room after it was closed up and then sucked all the air out it would insure no dust would collect. but you'd have to suck out EVERY dust particle to do that completely. did you know that the rest of dust, besides the skin, is dirt, mite residue, and star dust? when comets go by they leave huge trails of dust and it all eventually gets pulled down to earth and it's what we clean off the table tops and bookcases!

Answer 2

Well, if there was something in that room to produce the dust, then yes, it would. Dust is flying around, and whatever collects dust grabs it out of the air. There would be no dust in this room unless the dust was already inside by the time it closed.

Answer 3

If the room is not used at all, there would be very little dust. But some was in the air when you closed it up, and that will settle on the furniture and floor with time.

Answer 4

If the room was completely clean then no, it wouldn't collect dust. But almost anything can create dust-dry wood, cracked concrete, sheddding fabrics- so pretty much if the room had everything removed, was covered floor to ceiling in marble, and completely sterilized- yes all dust would disappear.

Answer 5

Probably not, unless the wall paint tended to flake ever so slightly over many years.

Answer 6

no
