Indoor air quality (IAQ) is compromised by pollutants such as dust, pollen, mold, mildew and volatile organic compounds (VOCs).
These pollutants can come from furnishings, laboratories, cleaning solutions and building occupants. Health problems can begin shortly after exposure to poor indoor air quality. Occupants may experience itchy eyes, headaches and fatigue. Long term exposure to poor indoor air quality can contribute to chronic respiratory illnesses such as asthma. For this reason, the market for dehumidification systems has been largely driven by concerns over indoor air quality and energy usage in commercial buildings. Ironically, one of the major causes of indoor air quality problems has been due to revised code requirements that have demanded for more outdoor air to be introduced into buildings.
