MJMurcott: Soil, pollen and various other really fine particles which can be blown about by the slightest breeze, meaning that they can get almost everywhere.
Palaeos: I know that inside buildings a lot of dust is composed of small shed skin particles. I’m allergic to this specific form of “dust” and to dust mites who feed on it.
bebeami: I occasionally get pretty bad allergies which affect things like my acne – my derm did some tests and informed me that the dust I’m most sensitive to is shed skin (gross right?). When indoors that’s a greater than you would expect percentage of the dust you’re seeing.
Deathbreak: I hate dust! I don’t want it building up in my home! You let dust build up, and before you know it, you have an army of dust bunnies plotting tho take over!
