The SoundAir visibly displays a flashing red light as soon as the concentration of CO2 in the room gets too high, showing when ventilation is required.

A SoundAir on the wall will display the air quality in the room. When a lot of people are gathered in the same room the air quality deteriorates. The effect is often unnoticeable until after a long while, and if sufficient ventilation
is not carried out in time then it can lead to drowsiness and reduced concentration and learning capacity.

The SoundAir measures the concentration of CO2 in ppm (parts per million) and displays a visible warning as soon as the concentration of CO2 is too high. The recommended level is 1000 ppm. SoundAir is designed for hanging on a wall and can be preset between 400 – 2000 ppm.
