Here are the consequences of a dirty air filter:
- Reduced Engine Performance: A clogged air filter restricts airflow, starving the engine of the oxygen it needs to burn fuel efficiently. This results in decreased power, leading to sputtering, stalling, and difficulty starting.
- Increased Fuel Consumption: A starved engine has to work harder to compensate for the lack of air, leading to higher fuel consumption.
- Engine Damage: When the engine struggles to breathe, it can overheat and cause damage to vital components like pistons and valves.
- Reduced Lifespan: A dirty air filter puts stress on the engine, ultimately shortening its lifespan.
Understanding Your Lawn Mower Air Filter
Before diving into the cleaning process, let’s understand the types of air filters commonly found in lawn mowers:

Foam air filters are the most common type and are often found in older and less expensive lawn mowers. They are usually cylindrical and feature a foam material with a porous structure that traps debris. Foam filters require regular cleaning and can often be reused.
Paper Air Filters
Paper air filters are typically found in newer and more advanced lawn mowers. These filters consist of a pleated paper element housed in a plastic or metal frame. While paper filters are generally more effective at filtering out fine particles, they are not reusable. They need to be replaced when they become dirty.
How to Clean a Foam Air Filter
Now that you understand the importance of a clean air filter, let’s walk through the cleaning process:
Step 1: Removing the Air Filter
- Locate the air filter: This is usually located under a plastic cover near the engine.
- Remove the cover: You may need to loosen a few screws or clips to access the filter.
