These air monitors display the carbon dioxide content in the air.

What is the ideal maximum indoor CO₂ level?
According to the German Federal Environment Agency, indoor air quality is categorised as follows:

• Good ambient air quality: < 800ppm
• Average ambient air quality: 800 to 1,000ppm
• Moderate ambient air quality: 1,000 to 1,400ppm
• Poor ambient air quality: > 1,400ppm

Regular and proper ventilation…

The German Federal Centre for Health Education and the Robert Koch Institute advise regular ventilation of offices, schools, flats… Indoor spaces in general. Aerosols provide a possible transmission path for Coronavirus SARS-CoV-2 and other viruses. They build up very quickly and disperse themselves in closed indoor spaces. Proper ventilation is important to prevent risk of infection and improve the indoor climate.

CO₂ monitors help you to monitor ambient air quality and support your regular ventilation. Most devices warn you using a traffic light system or alarm sounds as soon as pre-programmed values are exceeded. This is important as people are generally very good at assessing a room’s air quality upon entry but they quickly lose this assessment ability as they adapt to smells, meaning that any deterioration is no longer noticed. We also tend to close windows too quickly when the temperature falls starkly and it gets colder.

The CO₂ monitors use sensors to measure the air’s CO₂ concentration and show the current carbon dioxide content range using the traffic light display.

These devices use sensors to measure the ambient air’s CO₂ content, the temperature and usually also the humidity and therefore help you to learn how to ventilate properly in order to contain viruses.
