  • Air Volume and Speed: The effectiveness of a leaf blower is often determined by its air volume (measured in cubic feet per minute, CFM) and air speed (measured in miles per hour, MPH). Higher CFM and MPH ratings generally mean better performance in clearing leaves and debris.
  • Build Quality and Durability: Look for blowers made from high-quality materials that can withstand wear and tear. A durable blower will last longer and require fewer repairs, making it a better long-term investment.
