Recently the efficiency of buildings has been improved . This makes them tighter and less well ventilated.
Scientific evidence has long been demonstarting an association between poor indoor air quality and respiratory diseases, including asthma and allergies.
The ventilation by opening the windows is insecure and ineffective, and at the same time leads to loss of energy, so all these circumstances make the mechanical ventilation obligatory for ensuring health and comfort of the inhabitants of the buildings
