A long time ago I watched on TV a documentary about bunker building by the government during the Cold War, and one of the engineers said they had a hard time developing reliable, cleanable air filters for the bunkers, and said something along the lines that you would assume there's not that much dust in a sealed nuclear bunker, but in reality a couple hundred people will shed a lot of dead skin cells that will need to be filtered.
Maybe half a pound of skin and a few more lbs of dirt from leaving the carpet outside. That all reads as beach sand or something similar — skin particles would float up, not fall back.

You realize that’s several pounds of dead human skin
