Indoor air quality monitor
Thanks to these carbon dioxide monitors, it is possible to determine whether the air we breathe is healthy or whether indoor ventilation needs improvement.
When we breathe, we expel CO₂, which accumulates in unventilated interiors. To give you an idea, the concentration level outdoors is approximately 420 ppm (parts of carbon dioxide per million), and indoors, it is considered excellent up to 700 ppm, according to health recommendations published in 2020.
The higher this figure, the more of the air we breathe has been previously breathed by someone else. And that dramatically increases the risk of contagion. But although it is a variable that is being given special attention in the wake of the coronavirus and air pollution, it affects many other aspects, such as tiredness, drowsiness, and concentration. Hence the importance of considering clean air free of harmful particles.
