What maintenance action should be taken to prolong the life of an air filter?

To prolong the life of an air filter, regular cleaning or replacement as necessary is essential. Air filters play a critical role in maintaining engine performance and efficiency by preventing dirt and debris from entering the engine. Over time, filters can become clogged with particles, which impedes airflow and can lead to decreased engine efficiency and potential damage.

Regular cleaning of reusable air filters helps maintain optimal airflow, ensuring that the engine operates efficiently. If the filter is disposable, replacing it at recommended intervals is vital for continued engine protection. By monitoring the condition of the air filter and addressing any buildup of dirt through cleaning or timely replacement, you can ensure that the engine receives the appropriate amount of air for combustion, thereby extending the life of both the filter and the engine itself.

Other methods, such as sealing a filter with tape or washing it with soap and water, can be harmful or ineffective in maintaining the air filter's integrity and functionality. Sealing can restrict airflow usually intended to be filtered, while soap and water may not be suitable for all types of air filters, risking damage rather than cleaning.
