In our blog we inform you about interesting facts about indoor air and air quality.

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.

Laser printers and copiers are an often underestimated factor for healthy breathing air in the office - they emit particulates, nanoparticles and pollutants. In this interview with Heike Krüger from the nano-Control Foundation, we talk about health risks, education and a current campaign.

Allergic asthma - definition, symptoms, causes, therapy

Millions of people around the world suffer from asthma and know the oppressive feeling of not being able to breathe easily. But how exactly is bronchial asthma defined, what are the typical symptoms and causes, and what can help to alleviate it in addition to the treatment prescribed by a doctor?

Allergies: What influence does the ambient air have?

The pollutants in the air can affect our health and trigger or intensify allergies, for example. Our lungs are one of the most obvious sufferers. But the nerves and not least the skin also suffer from air pollution. What types of allergies are there, what is anaphylaxis and what role do histamines play?

Thick air in the office - how a good indoor climate ensures efficiency

In Germany, air quality at the workplace is governed by the Workplace Ordinance - specifically the workplace regulations. However, "healthy air to breathe" is often not very good in the office. On the contrary, the air is thick, especially in open-plan offices. How is it possible to ensure their performance through a good indoor climate?

How heating with wood pollutes the air we breathe

How can pollutant emissions in cities be reduced sustainably? The public debate focuses too much on the mobility revolution. But the air we breathe, especially in residential areas, is not only polluted by traffic: In the winter months, heating with wood, coal and pellets contributes to increased particulates- and pollution.

How noise affects people's health

Everyone knows it: noises such as loud music, an aeroplane or a train trigger different reactions. Noise is perceived subjectively by everyone. But one thing is clear: noise affects our health because we cannot get used to it. But which noise sources are particularly harmful, and how is noise actually measured?

Air pollution in Europe: Enormous pressure to act despite small progress

The European Environment Agency (EEA) has examined air pollution in Europe in its annual report. The evaluation of 4,000 measuring points showed that air pollution caused by particulates, nitrogen dioxide and ground-level ozone endangers the health of the vast majority of city dwellers. What can be done about it?

Many of the dangers posed by air pollutants such as particulates are undisputed and well known. But besides these health reasons to do more for good air quality, there are also economic reasons: The solar yield can be significantly reduced by air pollution and particulates - and that in two ways.

How a forest fire can trigger asthma

Rising temperatures as a result of climate change increase the risk of forest fires and make it more difficult to contain them. The resulting particulates pollution is a particular problem for people who are already at risk of asthma. What is the connection between asthma and forest fire particulate matter?
