Secondary filters, also called inner filter, smaller air filter, or safety air filter. The secondary filter acts as an available filter and protects the engine when the primary filter is detached from the air filter housing during maintenance, and is usually installed inside the primary filter. Even if the main filter is damaged or replaced, it can also play a protective role. Never operate the engine with only the safety filter. The safety filter is not a backup filter! Compared with the primary filter, the safety filter is more open, less restrictive and less efficient. Secondary filters do not improve the overall efficiency of the air cleaner. The secondary filter protects the engine from potential damage to the main filter – cleaning, incorrect installation, mismatched “fit” or installation of the wrong size filter.
