The air filter removes any dirt, dust or other debris before they can enter the engine. This debris can easily plug the carburetor, making the blower run poorly or not start at all. If dirt gets into the engine, serious damage can occur. The air filter should be inspected often, and replaced at least once per year (or more often, as needed).
Let's get started.
