Invisible gases and particles in the air you breathe.

We breathe more than 20,000 times a day without knowing what substances are in the air, where and how they originate, what effects they have on us, or what the limit values are. We’ve compiled information for you on the limit values for gases, particles, and pollutants in indoor air.

These substances affect your health and well-being — learn all about the quality of the air you breathe

Here you can learn about the invisible gases and particles present in the air you breathe. We explain how the various substances and compounds are formed and what effects they have on you. You’ll also find a summary of the often complex definitions of limit values, such as those set by the Federal Environment Agency or the WHO. Based on this, we provide recommendations for sustainably improving your indoor air quality.
