Many factors affect indoor air quality.  These factors include poor ventilation (unbalanced distribution – lack of outside air), problems controlling temperature, high or low humidity, recent remodeling, contaminated airborne water mist, and other activities in or near a building that can affect the fresh air coming into the building. Sometimes, specific contaminants like dust from construction or renovation, mold, cleaning supplies, pesticides, or other airborne chemicals (including small amounts of chemicals released as a gas over time) may cause poor indoor air quality.

The right ventilation and building care can prevent and fix indoor air quality problems. Although OSHA does not have indoor air quality standards per se, it does have standards about ventilation and standards on some of the air contaminants that may be involved in indoor air quality problems.

Indoor air quality is a concern in many schools due, in part, to the age of students and poor condition of a number of school buildings. School indoor air quality is particularly important as it may affect the health, performance and comfort of children.
