A lawn mower’s air filter is an essential component that helps keep the engine running smoothly and efficiently. It prevents dirt, dust, and debris from entering the engine and causing damage. Over time, the air filter can become clogged with dirt and debris, which can reduce the engine’s performance and cause it to overheat. Therefore, it’s essential to clean the air filter regularly to ensure that your lawn mower continues to run smoothly. Here’s how to clean the air filter on your lawn mower in a few simple steps.

Materials Needed:


Compressed air can

Clean rag or towel

Dish soap

Bucket or container


Step 1: Turn Off the Lawn Mower

Before you begin cleaning the air filter, make sure that your lawn mower is turned off and the spark plug is disconnected. This will ensure that the engine is completely cool and that there is no risk of injury.

Step 2: Locate the Air Filter

The air filter is typically located on the side or top of the lawn mower’s engine. Refer to your lawn mower’s manual if you are unsure where the air filter is located.

Step 3: Remove the Air Filter Cover

Using a screwdriver, remove the air filter cover and set it aside. Be careful not to lose any screws or other small components.

Step 4: Remove the Air Filter

Once the air filter cover has been removed, take out the air filter. Inspect it for signs of damage or excessive wear. If the air filter is damaged, it will need to be replaced rather than cleaned.

Step 5: Clean the Air Filter

Using compressed air can blow any loose dirt or debris off the air filter. Be careful not to damage the filter material. Then, prepare a bucket or container with warm water and a few drops of dish soap. Soak the air filter in soapy water for 10-15 minutes to loosen any remaining dirt and debris.

Step 6: Rinse the Air Filter

After the air filter has soaked, rinse it thoroughly with clean water to remove any remaining soap and debris. Gently squeeze the air filter to remove any excess water.

Step 7: Dry the Air Filter

Allow the air filter to air dry completely before reinstalling it. Do not use any heat sources to speed up the drying process, as this can damage the filter material.

Step 8: Reinstall the Air Filter

Once the air filter is completely dry, reinstall it in the lawn mower. Make sure it is properly seated and secure.

Step 9: Reinstall the Air Filter Cover

Finally, reattach the air filter cover with the screws or other fasteners that you removed in step 3.


Cleaning the air filter on your lawn mower is a simple and straightforward process that can help keep your lawn mower running smoothly and efficiently. Regular cleaning of the air filter can extend the life of your lawn mower’s engine and help prevent costly repairs. Be sure to clean the air filter at least once a year or more frequently if you frequently use your lawn mower in dusty or dirty environments. Refer to your lawn mower’s manual for specific instructions and recommendations regarding air filter maintenance.
