Most of the modern applications focus on measuring outdoor air pollution. This is indeed very important and useful, however most of the time in person’s life is spent indoors. This is also an environment, where one is able to influence the climate using various air purifying instruments.

The negative change of indoor climate is often influenced by normal human behavior. For example levels of CO2 are increased in heavily occupied spaces with poor ventilation, levels of PM increase when cooking or smoking.

This points towards a greater need to monitor these air quality levels and be able to react to them in a timely manner.
