Pure air is vitally important

We spend over 90% of our lives indoors. So the indoor climate is very important for our health.

Every day we inhale tiny dust particles which swirl around the house. These particles are also known as particulate matter. They are invisible to the naked eye, but that doesn't make them any less dangerous.

Research conducted by the World Health Organization (WHO)* shows that high concentrations of fine particles in the air are a particular cause of health problems.

Fine particles increase the risk of asthma and allergic reactions. Furthermore, they are an important cause of respiratory problems in young children.

A high concentration of fine particles in the air can therefore harm your health and that of your housemates.
