Indoor air quality (IAQ) refers to the air quality as it relates to the health and comfort of occupants within and around buildings and structures. Health effects from poor indoor air quality may be experienced soon after exposure or possibly not until years later. Understanding and controlling common pollutants to improve your IAQ can help reduce health problems and ease concerns.
