Challenges for Indoor Air Quality Management

We live indoors. In the developed countries, people spent80-90% of time in buildings. Therefore, among the environmentalfactors, indoor air quality (IAQ) is a significant,if not the most significant, factor affecting human health.Scientific evidence has indicated that indoor air can bemore seriously polluted than the outdoor air in even thelargest and most industrialized cities. Indoor air pollutioncauses long- and short-term health problems and, dependingon the severity, can even make staying indoorsvery uncomfortable. Management of IAQ is a complicatedtask due to complexity of pollution sources and alimited number of measures applicable such as reducingcontaminants at the source, improving ventilation, and,when relevant, purifying the indoor air
