WEBCFM is a ‘ft 3 per minute’ unit. That’s why we need to divide the total volume by 60; hence 4,800/60 = 80 CFM. Answer: You need an 80 CFM airflow (for 300 sq ft standard room and 2 ACH). Here’s a neat CFM calculator that calculates CFM based on room area, ceiling height, and the number of air changes per hour (ACH).
