How much dust does an average non smoking person inhale a day?

An average non-smoking person inhales about 7 to 10 liters of air per minute, which translates to approximately 10,000 to 15,000 liters of air each day. Dust particles in the air can vary widely, but studies suggest that a person might inhale around 1 to 2 milligrams of dust daily. This amount can fluctuate based on environmental conditions, such as location and cleanliness.
