Indoor Air Quality Surveys

Indoor air quality (IAQ) broadly refers to the environmental characteristics inside buildings that may affect human health, comfort, or work performance. We monitor IAQ because we spend approximately 90% of our time breathing “indoor air”. Unlike outdoor air, indoor air is recycled continuously causing it to trap and build up pollutants. IAQ characteristics include the concentrations of pollutants of indoor air, as well as air temperature and humidity.

Poor IAQ contributes to both short and long term health issues which can lead to decreased productivity, absenteeism, and possible litigation. Typical symptoms associated with poor indoor air quality include eye, nose, and throat irritation, headache, nausea, dizziness, and fatigue. In some cases exposure to indoor air pollution can lead to acute and chronic respiratory illnesses including asthma, lung cancer, pneumonia, systemic hypertension, chronic obstructive pulmonary disease (COPD), Legionnaires’ disease, and humidifier fever.

In some countries indoor air quality can be worse than outdoor air quality, especially when we consider the amount of time people spend indoors versus outdoors.
