Why is Indoor Air Quality Important
People spend around 90% of their time indoors, and daily exposure to indoor air pollutants may occasionally be more than 10 times higher than outdoor pollutants. It is estimated, for instance, that up to 20% of the population suffers from asthma and other allergic diseases caused by substances typically present in indoor environments. In addition, indoor pollutants such as tobacco smoke, radon, asbestos and formaldehyde may substantially contribute to the increase of cancer incidents in the population. The World Health Organization (WHO) estimates that 700,000 people per year die from poor breathing conditions. Clearly, IAQ has a significant impact on people’s comfort and health.
