Cubic Feet per Minute (CFM) is a measurement quantifying the volume of air a leaf blower can move in one minute. This metric represents the blower’s ability to clear debris from a given area. For example, a blower rated at 400 CFM can displace 400 cubic feet of air every 60 seconds.
The CFM rating is a critical factor when selecting a leaf blower. Higher CFM values indicate a greater capacity to move larger volumes of leaves and other yard waste. Historically, this specification has been a primary indicator of blower power, allowing consumers to differentiate between models intended for light residential use and those designed for heavy-duty commercial applications.
