Fresh air requirement for a room can be calculated using the formula: Fresh air (CFM) = volume of the room (cubic feet) × air changes per hour. Determine the volume of the room by multiplying the length, width, and height measurements. The recommended air changes per hour vary depending on the room function and occupancy, typically ranging from 4-8 for most spaces.
