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

June 09, 2016

According to an urban legend, 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 affecting your indoor air quality?

The Source

There are only two areas 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 is made up of soil particles and pollen brought in on our shoes or through open doors and windows. This contributes to about two-thirds of the dust in your house.

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 have 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 miniscule arachnids and their top food source is dead human skin cells and they make up a majority 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 managing a successfully humidified home, you’re able to decrease their impact.
