Since covid, indoor air quality has received much more attention. That is how CO2 meters made their way to the general public. But why do CO2 meters remain important, even after the pandemic?

Advantages of a CO2 meter

It is important to measure CO2 in homes and offices but also in schools and public buildings. A CO2 meter boasts a number of advantages in terms of:

  • Air quality: CO2 measurements are a good indicator of the general air quality in enclosed spaces. CO2 and other polluting substances tend to build up when the ventilation is poor to the detriment of air quality.
  • Health and well-being: a high concentration of CO2 in the air often leads to health ailments such as headaches, fatigue, dizziness and problems with concentration and attention – issues that will only get worse over time.
  • Productivity and cognitive functions: Studies have shown that high CO2 levels in an interior have a negative effect on the productivity and cognitive functions of the occupants. Healthy indoor air is consequently essential for a good learning and working environment.
  • Virus spreading prevention: It has become clearer since the pandemic that good ventilation of indoor spaces is key to preventing viruses from spreading.
  • Energy efficiency: You can optimise ventilation systems by measuring CO2 and save energy and costs.

Research shows: CO2 levels in classrooms are too high 15 per cent of the time, even with the windows open

Smart CO2 meter with extra features

At home for yourself and your family, at work for your colleagues or employees: a CO2 meter offers nothing but benefits, for your comfort as well as your health and your wallet. So even after covid, a CO2 meter remains relevant. That is why we at Arizo also distribute our own Smart CO2 meter.

Besides CO2 and humidity, particulate matter and VOCs (volatile organic compounds) can also seriously affect air quality and health. That is why our Smart CO2 meter not only provides highly reliable CO2 measurements but is also equipped with extra sensors for volatile organic compounds (VOCs) and particulate matter. The quality of this meter was tested and approved in our in-house lab.

CO2 meters mandatory in some spaces

Did you know that CO2 meters are mandatory in rooms larger than 15 square metres where people stay for more than 15 minutes? From 2025, an air quality label is also required. Ask us for advice if you would like to know more.
