What is Dust Made of and How Does It Affect Your Indoor Air Quality?

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 contribute to dust, dust is actually multiple things. So what exactly is dust composed of and how is it hurting your indoor air quality?

The Source

There are only two areas that dust can stem 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 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 various 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 too.

Dust Mites

Whenever we speak of dust, we must also talk about dust mites. Dust mites are little arachnids and their primary food source is dead human skin cells and they make up a huge percentage 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 thrive in humidity, so by maintaining a successfully humidified home, you’re able to lower their impact.
