As unique as every building is in terms of its architecture, its need for ventilation and air conditioning systems is just as individual. The interiors must be as free as possible from unwanted odors, exhaust fumes, dust and fine dust, pollen and other pollutants in order to provide people with a healthy environment. And every building has very different requirements in terms of ventilation and air filtration. It is not only the regulation of fresh air in public buildings with different levels of traffic, such as universities or airports, that is a challenge.
