What is Dust Made of and How Does It Affect Your Indoor Air Quality?06/09/2016According to an old story, dust is made up of human skin. Of course in reality, it’s not true. Although human skin does make up some of what is dust, dust is actually various things. So what exactly is dust composed of and how is it changing your indoor air quality? The Source There are only two areas that dust can stem from, indoors and outdoors, and we are the ones that are bringing dust inside from the outdoors. The outdoor part of dust consists of soil particles and pollen brought in on our shoes or through open doors and windows. This adds up to about two-thirds of the dust in your house. The indoor source of your dust is a number of assorted 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 also. Dust Mites Whenever we bring up dust, we must also talk about dust mites. Dust mites are tiny arachnids and their main 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 prosper in humidity, so by managing a properly humidified home, you’re able to lower their impact. What Can You Do?
