The air that we breathe has a crucial effect on our health and well-being. Since we spend on average more than 90% of our time indoors, the air quality inside is of utmost importance. The presence and size of particulate matter (PM) or fine dust is a determining factor in air quality and is directly linked to potential health problems.
Once inhaled, these particles can contribute to the spread of microbial contaminants, such as mould, pollen and allergens. In addition, they can affect the heart and lungs and cause serious physiological problems.
Extensive evidence from WHO indicates that concentrations of fine dust currently found in most cities in developed countries around the world results in a serious health risk*.
