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)
“Spread outward. Crack the round dome. Break through.
Have liberty not as the air within a grave
Or down a well. Breathe freedom, oh, my native,
In the space of horizons that neither love nor hate.”
—Wallace Stevens (1879–1955)
“This fellow is wise enough to play the fool,
And to do that well craves a kind of wit.
He must observe their mood on whom he jests,
The quality of persons, and the time,
Not, like the haggard, check at every feather
That comes before his eye. This is a practice
As full of labor as a wise man’s art.”
—William Shakespeare (1564–1616)
