In most places in the Netherlands, the atmospheric carbon dioxide level in the open air is about 400 ppm. Once a group of people enters a space, the amount of carbon dioxide will start to increase significantly, with which a doubling is quite normal. The presence of people, computers, printers and other devices leads to indoor air pollution, manifesting int. al. in high PPM carbon dioxide levels. The carbon dioxide level is a recognized parameter for indoor air quality and is often the unexpected cause of many health problems.
A limited freshness of the air increases the risk of: headaches, allergies, middle ear infection, dry eyes, prickly throat, respiratory infections, asthma, pneumonia, loss of concentration and meningitis.
Especially in (confined) spaces where people reside and / or come together, high carbon dioxide emissions are created, such as in: nurseries, schools, hospitals, healthcare bureaus, offices, public buildings, children’s bedrooms, hotels, conference rooms, homes with moisture and ventilation problems, asylum seeker centers, prisons, fitness centers and gyms, theatres, cinemas and libraries.
