A: Airflow quantifies the amount of air a ceiling fan delivers and is measured in CFM which stands for cubic feet per minute. CFM measurements are taken when a fan is on high speed, then that number is divided by the watts used. This means that the higher the CFM, the more efficient the fan, and the more air it moves.
