What is Dust Made of and How Does It Affect Your Indoor Air Quality?06/09/2016According to folklore, dust is made up of human skin. Of course in reality, it’s not true. Although human skin does contribute to dust, dust is actually various things. So what exactly is dust made of and how is it hurting your indoor air quality? The Source There are only two locations that dust can form 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 adds up to about two-thirds of the dust in your home. The indoor source of your dust is a number of different things. A small 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 as well. Dust Mites Whenever we speak of dust, we must also talk about dust mites. Dust mites are tiny arachnids and their top food source is dead human skin cells and they make up a large part of dust. Dust mite droppings are the most common cause of allergy and asthma symptoms according to the American Academy of Allergy, Asthma & Immunology.
