How much air does the average person need in a day?

The average person needs about 10,000 to 12,000 liters of air per day, depending on factors like activity level and health. This amount translates to roughly 20 to 25 breaths per minute at rest, leading to about 6 to 10 liters of air inhaled per breath. Active individuals may require significantly more air due to increased oxygen demands during physical exertion.
