Definition of the term CFM (Cubic Feet per Minute)

Measure of volume of air. When testing systems, find the CFM by multiplying the face velocity (amount of air passing through the face of an outlet or return) times the free area (the total area of the openings in the outlet or inlet through which air can pass) in square feet.

The home inspection is a very important step when purchasing a home.
