Why your 3 pm meeting feels so tiring

Put twelve people in a meeting room, close the door, and within an hour the carbon dioxide level can more than double. Nobody can see it or smell it, but many people feel it as heaviness and drowsiness.

A Caleedo air sensor in the room measures CO₂ every few seconds. When it crosses the limit you set, often around 1,000 ppm, the facility team gets an alert to increase fresh air.

Over a month, the report shows which rooms get stuffy and when, so you can fix ventilation where it matters instead of guessing.
