Indoor air quality (IAQ) is a term which refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of building occupants.
IAQ can be affected by gases (including carbon monoxide, radon, volatile organic compounds), particulates, microbial contaminants (mould, bacteria) or any mass or energy stressor that can induce adverse health conditions. Source control, filtration and the use of ventilation to dilute contaminants are the primary methods for improving indoor air quality in most buildings.
Determination of IAQ involves the collection of air samples, monitoring human exposure to pollutants, collection of samples on building surfaces and computer modelling of air flow inside buildings.

Famous quotes containing the words indoor, air and/or quality:
“As a man grows older, his ability to sit still and follow indoor occupations increases. He grows vespertinal in his habits as the evening of life approaches, till at last he comes forth only just before sundown, and gets all the walk that he requires in half an hour.”
—Henry David Thoreau (1817–1862)
“I wonder whether mankind could not get along without all these names, which keep increasing every day, and hour, and moment; till at the last the very air will be full of them; and even in a great plain, men will be breathing each other’s breath, owing to the vast multitude of words they use, that consume all the air, just as lamp-burners do gas.”
—Herman Melville (1819–1891)
“All men are lonely. But sometimes it seems to me that we Americans are the loneliest of all. Our hunger for foreign places and new ways has been with us almost like a national disease. Our literature is stamped with a quality of longing and unrest, and our writers have been great wanderers.”
—Carson McCullers (1917–1967)
