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 completely factual. Although human skin does contribute to dust, dust is actually a variety of things. So what exactly is dust composed of and how is it affecting 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 forms from soil particles and pollen scuffled 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 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 main food source is dead human skin cells and they make up a majority of dust. Dust mite droppings are the most prevalent cause of allergy and asthma symptoms according to the American Academy of Allergy, Asthma & Immunology. Dust mites also prosper in humidity, so by maintaining a successfully humidified home, you’re able to cushion their impact. What Can You Do?
