Question

Circulation of air remove still stale air and bring things in fresh air true or false

Answer 1

Answer:

Stale air is no longer fresh and can have an unpleasant smell. When indoor air starts to smell stale or feel stuffy, it is usually due to a buildup of certain chemicals as well as humidity in the air. The ratio of airborne contaminants to oxygen starts to increase because of a lack of fresh air.
