Causes and Sources of Indoor Air Pollution

The relevance of indoor air quality to our well-being is hardly considered. This makes an important contribution to improving physical and mental performance and creating a comfortable living space. Research shows that indoor air can be up to five times more polluted than outdoor air. We inhale dust, mold, smoke, bacteria, viruses and animal hair. This can lead to health problems ranging from headaches, eye irritation, dizziness and fatigue to breathing problems.

The causes and sources of indoor air pollution are many and varied. Many pollutants are chemical in nature, for example:

Burning candles or the use of scented oils in lamps are the cause of many polluting emissions, especially in winter. Fireplaces, such as chimneys or stoves, also pollute indoor air. The same applies to cooking, especially with gas flames:harmful substances are released during combustion and frying.

Pollutants that enter the home from the outside air, such as nitrogen dioxide and particulate matter. Once the dirt comes in, it is collected, especially in the new airtight, energy-efficient buildings.

Materials for the construction of buildings and for interior decoration, such as paints, glues, furniture, decoration materials, but also cleaning agents and tobacco smoke.

There are also harmful substances of a biological nature such as fungi, bacteria, allergens. And humans themselves also influence the quality of the indoor air, because we exhale carbon dioxide.
