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

Urban legend and other internet searches may persuade you that dust is made up of human skin, but that is not completely accurate. Skin makes up a tiny percentage of dust, but it is actually a plethora of things. If it’s not skin, what is dust consisting of and how is dust affecting your home’s indoor air quality?


Dust in your house derives from two places, outdoors or indoors. The dust from the outdoors is transferred in by humans. This dust consists of soil or pollen that is brought in on our clothing or through open windows. The dust brought in from the outside is approximately two-thirds of the dust in our homes.

Dust created indoors is made of a number of unique sources. A very tiny part is really human skin. The majority of indoor dust is made up of furniture and carpet fibers and, if you have a pet, pet dander and fur.

Dust Mites

Where there is dust there is also dust mites. If you’re feeling courageous, a swift search online will show you what they look like. If you’re not feeling so curious, imagine a tiny arachnid that’s main source of food is dead human skin cells. Dust mites make up a major portion of dust and their droppings are the leading cause of asthma and allergy symptoms according to a study completed by the American Academy of Allergy, Asthma & Immunology. While they are feasting on dead skin cells they are thriving in humidity. Managing the correct humidity of your home can decrease the impact of dust mites.
