What is Dust Made of and How Does It Affect Your Indoor Air Quality?06/09/2016 Urban fables and various internet sites may persuade you that dust is made up of human skin, but that is not completely true. Skin makes up a tiny percentage of dust, but it is actually a combination of things. If it’s not skin, what is dust consisting of and how is dust affecting your home’s indoor air quality? Sources Dust in your house derives from two places, outdoors or indoors. The dust from the outdoors is carried in by us. This dust consists of soil or pollen that is attached on our clothing or through open windows. The dust brought in from the outside is about two-thirds of the dust in our homes. Dust formed indoors is made of a variety of different things. A tremendously minimal part is actually 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 quick search online will show you what they look like. If you’re not feeling so curious, picture a tiny arachnid that’s primary 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 dining on dead skin cells they are thriving in humidity. Preserving the ideal humidity of your home can reduce the impact of dust mites. What are the solutions?
