Cubic Feet per Minute (CFM). A measure of how much air moves in a minute, measured in cubic feet (the amount of air which fits inside a box 1 foot wide, one foot high, and one foot long). Most vacuums and fans are rated in terms of CFM. It tells how much air gets moved in a given length of time. More CFM is usually better, but it usually comes at the cost of more noise.
