CFM measures air volume; MPH measures air speed. Real blowing performance depends on both plus nozzle shape and how the air reaches the debris.
What matters most
High CFM is valuable for moving broad piles, while high MPH helps break stuck material loose. A balanced blower is generally more useful than one optimized for a single laboratory number.
Where buyers get tripped up
Manufacturers may quote maximum CFM and MPH under different nozzle configurations, so two headline numbers are not always directly comparable.
What to verify before buying
Check whether ratings use the same nozzle, compare turbo and sustained modes, and match the specification to the debris you move most often.
How we research leaf blowers
We compare rated airflow and air speed, nozzle configuration, sustained versus turbo output, battery capacity or engine class, tool weight, ergonomics, noise, runtime, and how well the format matches the debris and property size.
Prices, specifications, firmware, and configuration-driven features can change. Check the current manufacturer page and local requirements before buying or installing equipment.
