Dust consists of particles in the atmosphere that come from various sources such as soil dust lifted by wind (an Aeolian process), volcanic eruptions, and pollution. Dust in homes, offices, and other human environments contains small amounts of plant pollen, human and animal hairs, textile fibers, paper fibers, minerals from outdoor soil, human skin cells, burnt meteorite particles and many other materials which may be found in the local environment.

Dust may worsen hay fever. Circulating outdoor air through a house by keeping doors and windows open, or at least slightly ajar, may reduce the risk of hay fever-causing dust. In colder climates, occupants seal even the smallest air gaps, and eliminate outside fresh air circulating inside the house. So it is essential to manage dust and airflow.

House dust mites are ubiquitous everywhere humans live indoors. Positive tests for dust mite allergies are extremely common among people with asthma. Dust mites are microscopic arachnids whose primary food is dead human skin cells. They do not actually live on people, though. It is probably not possible to entirely eradicate them. They and their feces and other allergens they produce are major constituents of house dust, but because they are so heavy they are not long suspended in the air. They generally are on the floor and other surfaces, until disturbed (by walking, for example). Sources suggest it could take somewhere between 20 minutes and 2 hours for them to settle back down out of the air. Dust mites are a nesting species that prefer a dark, warm and humid climate, and they therefore flourish in mattresses, bedding, upholstered furniture, and carpets. Their feces include enzymes that are released upon contact with a moist surface, as happens when a person breathes it in, and these enzymes actually kill cells within the human body. Sources suggest that house dust mites did not become a problem until humans began to use textiles, such as western style blankets and clothing.

Eli Young Band is an American country music band based in Denton, Texas. The band is composed of Mike Eli (vocals, guitar), James Young (guitar), Jon Jones (bass guitar), and Chris Thompson (drums). They released their self-titled debut album in 2002, followed by the Carnival records release Level in 2005. Their third album, Jet Black & Jealous, was released in 2008 by Universal South Records. A second major-label album, Life at Best, was released in 2011 by Republic Nashville; it includes their first #1 hit, "Crazy Girl".

Mike Eli and James Young met each at the University of North Texas when they became dorm roommates their freshman year. They played guitar and eventually began writing and singing songs together; they formed the acoustic duo, Eli & Young, while attending the University of North Texas. Chris Thompson and Jon Jones joined them later on and they became the Eli Young Band.

They released their first album in 2002, self-titled "Eli Young Band". In 2005 they released "Level" on Carnival Records and opened shows for Miranda Lambert. National exposure on CMT and GAC helped them begin to build a following well outside of their touring base. They sold as many as 2,000 tickets a night in multiple markets. In late 2006 they released Eli Young Band Live At the Jolly Fox located in Huntsville, Texas. Early in 2007, they signed a management deal with George Couri and C3 Management. Their plans included a rigorous tour schedule and key opening spots with Pat Green, Robert Earl Keen, and Jack Ingram, as well as a spot on the 2007 Austin City Limits Music Festival.
