Indoor air quality

Indoor Air Quality (IAQ) deals with the content of interior air that could affect health and comfort of building occupants.

The IAQ may be compromised by microbial contaminants (mold, bacteria), chemicals (such as carbon monoxide, radon), allergens, or any mass or energy stressor that can induce health effects.

Recent findings have demonstrated that indoor air is often more polluted than outdoor air (albeit with different pollutants) although this has not changed the common understanding of Air pollution.

In fact, indoor air is often a greater health hazard than the corresponding outdoor setting.

Using ventilation to dilute contaminants, filtration, and source control are the primary methods for improving indoor air quality in most buildings.
