Throughout our life we spend more and more time inside buildings (more than 70% of our lifetime). Apart from the time we spend for relaxation, sleep and housework inside our houses we also spend much time for our job, entertainment and other activities inside buildings. The good air quality of an indoor space has a positive influence on people being inside. On the contrary the poor air quality affects not only the health and the mood of the people but also their working effectiveness.
