Cleaning your lawn mower’s air filter before storage is crucial for maintaining its performance and longevity. To clean the air filter effectively, remove it from the mower, inspect for damage, and use the appropriate cleaning method depending on the filter type—foam or paper. Proper maintenance ensures your mower runs smoothly when you need it next season.
How to Clean a Lawn Mower Air Filter?
Cleaning the air filter is a straightforward process, but it varies slightly depending on whether you have a foam or paper filter. Here’s a step-by-step guide:
Step 1: Gather Necessary Tools
Before you start, make sure you have the following tools and materials on hand:
- Screwdriver or wrench (to remove the air filter cover)
- Mild detergent or soap (for foam filters)
- Clean water
- Replacement filter (if necessary)
- Compressed air (for paper filters)
Step 2: Remove the Air Filter
- Turn off the lawn mower and ensure it is cool.
- Locate the air filter cover, usually on the side of the engine.
- Use a screwdriver or wrench to remove the cover.
- Carefully take out the air filter. Note its orientation for easy reinstallation.
Step 3: Inspect the Air Filter
- Foam Filters: Check for tears or significant wear. If damaged, replace it.
- Paper Filters: Look for excessive dirt or damage. Replace if necessary.
Step 4: Clean the Air Filter
For Foam Filters:
- Wash in Soapy Water: Use mild detergent and warm water to wash the foam filter. Gently squeeze to remove dirt and debris.
- Rinse Thoroughly: Rinse the filter under clean water until all soap is removed.
- Dry Completely: Allow the filter to air dry completely. Avoid using heat sources that could damage the foam.
- Oil the Filter: Lightly coat the dry filter with engine oil to improve dust capture. Squeeze out any excess oil.
For Paper Filters:
- Tap to Remove Dirt: Gently tap the filter against a hard surface to dislodge dirt.
- Use Compressed Air: Blow air from the inside out to clear remaining debris. Be careful not to damage the filter.
Step 5: Reinstall the Air Filter
- Place the clean or new air filter back in its housing, ensuring it’s seated correctly.
- Secure the air filter cover with screws or clips.
Why is Air Filter Maintenance Important?
Regular air filter maintenance is critical for several reasons:

Common Mistakes to Avoid
