What is Dust Made of and How Does It Affect Your Indoor Air Quality?06/09/2016 Urban legend and several internet sites could inform you that dust is made up of human skin, but that is not completely accurate. Skin makes up a minuscule percentage of dust, but it is honestly 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 comes from two places, outdoors or indoors. The dust from the outdoors is transferred in by people. 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 almost two-thirds of the dust in our homes. Dust formed indoors is made of several of different things. A very minimal component 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 bold, picture 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 dining on dead skin cells they are thriving in humidity. Preserving the proper humidity of your home can minimize the influence of dust mites. What are the solutions?
