What is Dust Made of and How Does It Affect Your Indoor Air Quality?06/09/2016 Urban legend and several internet searches could tell you that dust is made up of human skin, but that is not entirely accurate. Skin makes up a very small percentage of dust, but it is honestly a combination of things. If it’s not skin, what is dust made of and how is dust affecting your home’s indoor air quality? Sources Dust in your house comes from two places, outdoors or indoors. The dust from the outdoors is brought 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 created indoors is made of several of diverse things. An extremely tiny 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 brave, a quick search online will show you what they look like. If you’re not feeling so brave, imagine a tiny arachnid that’s first source of food is dead human skin cells. Dust mites make up a major portion of dust and their droppings are the top 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 decrease the impact of dust mites. What are the solutions?
