CASE: RISING CO2 LEVELS MAKE THE AIR STUFFY
As CO2 levels rise, you get less and less oxygen in each breath. This can cause a students to feel sleepy, tired, or less focused. At more extreme levels, carbon dioxide can give them a headache and make them feel dizzy. As the study showed, higher CO2 levels can make the air stuffy and lower the energy levels. In a room without windows or ventilation it could even create more dangerous levels: 40,000 ppm (4.0%) of CO2 is an immediate danger to life or health (source; IDLH); 50,000 ppm (5.0%) causes strong respiratory stimulation, dizziness, confusion, headache, and shortness of breath, while 80,000 ppm (8.0%) causes dimmed sight, sweating, tremors, unconsciousness, and possible death. All Greentech Air Purifiers remove CO2 gases from the air and prevent dangerous levels to rise.
