Research shows that student concentration and test scores drop significantly when CO2 exceeds 800 ppm.

Many schools operate in the red zone for most of the day because of outdated ventilation systems.

We need mandatory CO2 monitors in every classroom to ensure students are learning in an optimal environment.

Nothing wrong with opening windows, for a quick air change and it is free
