What is Dust Made of and How Does It Affect Your Indoor Air Quality?06/09/2016 Urban legend and other internet pages could inform 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 actually a plethora 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 living space derives from two places, outdoors or indoors. The dust from the outdoors is carried in by humans. This dust consists of soil or pollen that is clinging 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 different things. A tremendously small component 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 simple search online will show you what they look like. If you’re not feeling so curious, imagine a tiny arachnid that’s primary source of food is dead human skin cells. Dust mites make up a large portion of dust and their droppings are the number one cause of asthma and allergy flare-ups 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 ideal humidity of your home can reduce the affect of dust mites. What are the solutions?
