The importance of good ventilation

Clean air in the home is very important for your health. 
Did you know, for example, that you need 25 m

3

 (25,000 

litres) of clean, fresh air per hour? Furthermore, the CO

-

laden stale air must also be removed from the dwelling. 
Good ventilation is therefore essential. Balanced 
ventilation controls this for you in a comfortable way.

Breathing, cooking, showering and visiting the toilet: all 
indoor activities generate moisture and result in a build-
up of stale air. Continual adequate ventilation is essential 
to refresh air in the home – and thus keep it healthy 
and comfortable. We would otherwise very quickly start 
suffering from moulds, bacteria, dust mites, damp spots 
and unwanted odours. But that is not all. What do you 
think about health problems like allergies, respiratory 
irritation and headaches? All issues that can affect your 
health, concentration, functioning and performance.
