What is Dust Made of and How Does It Affect Your Indoor Air Quality?06/09/2016According to an urban legend, dust is made up of human skin. Of course in reality, it’s not correct. Although human skin is a part of dust, dust is actually various things. So what exactly is dust composed of and how is it hurting your indoor air quality? The Source There are only two areas that dust can form from, indoors and outdoors, and we are the ones that are bringing dust inside from the outdoors. The outdoor part of dust is made up of soil particles and pollen brought in on our shoes or through open doors and windows. This makes up about two-thirds of the dust in your house. The indoor source of your dust is a number of different things. A tiny part of which is, in fact, human skin. A majority of it is fibers from your carpet, furniture or bedding, and if you include a pet, there is also some pet dander and fur too. Dust Mites Whenever we speak of dust, we must also talk about dust mites. Dust mites are little arachnids and their primary food source is dead human skin cells and they make up a majority of dust. Dust mite droppings are the most common cause of allergy and asthma symptoms according to the American Academy of Allergy, Asthma & Immunology.
