A graph generated by Aranet’s iOS app showing the peaks and declines in CO2 levels throughout the day. My day was full of yellow and red levels of CO2, and only truly got to a healthy level of CO2 in the evening — when we arrived at our hotel.

   Peaks of the day:
   • In a lounge as we ate breakfast (peaked at 1731 ppm);
   • During our flight to São Paulo (peaked at 1568 ppm during takeoff, decreasing to 829 ppm when we landed);
   • Car rides with the AC on (5352 ppm — the peak of the day —, 2857 ppm, 2514 ppm, 4657 ppm, 4069 ppm). Air recirculation is the main culprit here (as many drivers use it to avoid the strong smell of air pollution).
