What is Dust Made of and How Does It Affect Your Indoor Air Quality? Posted June 9, 2016 According to an urban legend, dust is made up of human skin. Of course in reality, it’s not completely factual. Although human skin does make up some of what is dust, dust is actually various things. So what exactly is dust made of and how is it changing your indoor air quality? The Source There are only two locations that dust can come from, indoors and outdoors, and we are the people that are walking dust inside from the outdoors. The outdoor part of dust forms from soil particles and pollen tracked in on our shoes or through open doors and windows. This makes up about two-thirds of the dust in your interior. The indoor source of your dust is a number of various things. A small part of which is, in fact, human skin. A large amount 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 bring up dust, we must also talk about dust mites. Dust mites are miniscule arachnids and their top food source is dead human skin cells and they make up a majority of dust. Dust mite droppings are the top cause of allergy and asthma symptoms according to the American Academy of Allergy, Asthma & Immunology. Dust mites also thrive in humidity, so by maintaining a successfully humidified home, you’re able to decrease their impact. What Can You Do?
