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 completely factual. Although human skin does make up some of what is dust, dust is actually a variety of things. So what exactly is dust composed 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 tracking dust inside from the outdoors. The outdoor part of dust consists of soil particles and pollen tracked in on our shoes or through open doors and windows. This contributes to about two-thirds of the dust in your interior. The indoor source of your dust is a number of different 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 own 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 primary 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. Dust mites also prosper in humidity, so by upholding a successfully humidified home, you’re able to decrease their impact. What Can You Do?
