Demand for quality indoor air continues to increase as we are spending more time indoors than ever before. IAQ issues can be complex due to the diversity of indoor environments. Poor air quality may cause tiredness, inability to concentrate, and even illness (i.e., Sick Building Syndrome). To address problems caused by poor IAQ, national and local governments have developed guidelines for acceptable indoor air quality. Assessing indoor air quality in buildings begins with IAQ investigations using professional grade measuring instruments as the first step in creating a healthier work environment.
