Our passion is air - in the truest sense of the word. In our air quality blog, we write for you about current topics related to breathing air, indoor air and sensors and air quality. For example, we classify the results of new studies on the health effects of polluted indoor air or provide information on limit values. In addition, we also work on our own studies with real-time data from our own air measuring device air-Q. The blog is therefore a guidebook, reference work and important source of information for well-founded facts about air quality.
Winter poses particular challenges for our indoor climate: temperature, heating and the correct regulation of humidity. This can lead to dangerous mold growth, while air that is too dry is detrimental to health. Find out what to look out for and what mistakes you should avoid here.
