Fresh air improves the quality of life
|
|
A human being usually consumes about one kilogram of food and two litres of water each day – but at least 15 000 litres of air. Of this, up to 90% may consist of indoor air. For air to be clean to breathe, it has to be replaced with outdoor air every two hours.
One of the indicators of sufficient ventilation is that indoor air stays fresh also in the bedrooms during the night. Other indicators include, among other things, efficient drying of the bathroom and sauna, and fresh air in the toilet. In addition, windows and other outer wall structures have to keep dry during the heating season.
Clean indoor air is vital in order to prevent respiratory illnesses. Good indoor air is of especially great importance for a person with allergies or hypersensitivity. Vallox Oy co-operates with the Finnish Allergy and Asthma Federation in the development of heat recovery units, aiming at fresh indoor air in homes, schools and offices.
