It's not only a problem in schools. I am shocked by how employers and employees do not care about stifled air and poor circulation in offices. I had to literally bring a CO2 meter in to show that the air in the office was not conducive of productivity and clear thinking. How many studies do we need that show people's basic thinking abilities starting to suffer as the CO2 ppm goes up? I have that CO2 meter at my home office. If it's above 700ppm, I open the window wider. There is a dollar amount attached to air quality, but most people just suffer through it like it's something that HAS to be suffered.
