Your leaf blower’s power should depend on your leaf removal project’s size and how much power you feel comfortable handling. Leaf blowers with less than 700 CFM are best for homeowners. Leaf blowers with more than 700 CFM are for professional use.  If you have a small yard that only gets a few dry leaf piles every year, there’s no need to pay for the extra power you don’t need. Leaf blowers with a CFM between 200 and 400 are suitable for small yards that need a light cleanup.  For larger yards that receive plenty of leaves every autumn, you’ll want to consider a leaf blower that can handle the demanding task. A leaf blower with a CFM between 400 and 700 should help you get the job done with ease. If you don’t feel comfortable operating such a powerful tool, stick to a leaf blower closer to 400 CFM.  Leaf blowers with more than 700 CFM are typically reserved for professionals and best left for commercial-level work. If you decide to opt for a leaf blower with more than 700 CFM, make sure you know how to operate the tool safely. Otherwise, call a professional.
