It acts as a backup to prevent dirt and debris from reaching the engine if the outer filter becomes damaged or is improperly installed, and it keeps the intake clean during filter service. The filter is engineered to plug quickly and alert the operator if the primary filter fails. It is recommended to replace the safety filter every third primary filter change, or sooner if a primary failure has occurred.
