Indoor Air Quality
“Indoor air quality” refers to how clean the air in a building is.
As buildings become more airtight and energy efficient, actively managing indoor air quality becomes more important. Some air pollutants, like carbon monoxide, are highly dangerous. Others, like volatile organic compounds, can cause short-term health problems as well as chronic ones.
Moisture management, adequate ventilation, and selection of low-VOC products are some of the best ways to ensure good IAQ.
