Abstract
An air filter for a motor-driven tool such as a portable motor-driven chain saw includes a prefilter through which aspirated air flows into a chamber partly defined by a cover that can be secured to the housing of the motor-driven tool. From this space, the air flows through a main air filter to the carburetor of the motor. The main air filter and the prefilter are configured as a one-piece double filter unit.
