Frequently Asked Questions
How much CO2 does a person exhale while resting?
A resting adult exhales roughly 20 liters of CO2 per hour, though this rises noticeably during physical activity.
Why does CO2 concentration matter indoors?
High indoor CO2 concentration is a sign of poor ventilation and is linked to drowsiness, headaches, and reduced concentration at elevated levels.
How much does CO2 rise in a small room?
4 people in a 50 cubic meter room for 2 hours adds about 160 liters of CO2, raising the concentration by roughly 3,200 parts per million if the room is not ventilated.
