The first line of defense against the dirt and debris churned up during mowing is a properly operating air filter on a gas-powered lawnmower. Dirt is prevented from entering the engine through the carburetor when the air filter is functioning well.
However, if the air filter becomes clogged, dirt and other debris can enter the engine, potentially causing start-up issues and shortening the engine’s life.
The foam air filter system uses only a foam filter, whereas the dual-element system uses a paper and a foam filter. Both air filter systems should be maintained repeatedly and more frequently if you work in dusty environments.
You’ll need to locate the air filter in your mower and remove the cover to inspect it. Check to see if the filter is too dusty or oily; it must be cleaned.

Cleaning Process Of A Dual Filter
1) Focus On The Filter’s Specifications
When cleaning an air filter, the first step is to do your homework. For more information on the various sections, consult internet resources or your user manuals.
This will assist you in understanding the model and obtaining various parts for your lawnmower. The air filters on some lawnmower types are pretty straightforwardly cleaned.
2) Plug Off The Lawnmower
After you’ve done your homework and are familiar with the brand and manufacture of your mower’s engine, as well as the parts that go into them, the next obvious step, which many people overlook, is to ensure sure the lawnmower is turned off and unplugged from the power source.
A lawnmower has various moving elements that work even when the engine is turned off, in addition to the engine. As a result, as a safety precaution, make sure the lawnmower is completely switched off and disconnected. Spark plugs are an essential component of an engine that allows it to start.
They’re usually seen near the machine’s front. Once you’ve located them, remove the wires connected to the spark plugs and disconnect them.
3) Target The Location Of Air Filters
Now, you have to locate the air filters. The air filter on a lawnmower is usually found towards the top of the engine, encased in a metal or plastic housing held with screws. The air filters can be removed by unscrewing the wing nut that secures the air filter housing. After that, remove the filter by lifting it out of the housing.
Remove the filter and wash it thoroughly with hot water and liquid soap until all greases are gone. Moreover, use a rinse-off technique to remove as much water as possible.
After you’ve finished rinsing, apply just the correct amount of engine oil to the air filter, as too much could cause difficulties with the exhaust system. As a result, the air filter is recommended to be squeezed to remove the excessive oil content.
4) Clean The Dual Air Filter
Clean the dual-element air filter, a cartridge with soap water and a brush after cleaning the pre-cleaner. Remove any material from the rubber gasket encapsulation that seals the air filter on the carburetor unit after the filter has been cleaned. Moreover, inspect the gasket for any tears or leaks; if any exist, seal it off properly.
5) Unscrew The Casing Carefully
Remove the air filter by unscrewing the casing and cleaning the rubber gasket on the inside. If your screws are corroded or broken, ensure you have a sufficient supply of the correct size. As a result, you must have the appropriate tools and resources before beginning the cleaning process.
Keeping track of all the parts and components, you take out is critical. So, the screws don’t go misplaced; keep them in a bowl. On the other hand, if necessary, use your phone to capture images or videos of each screw and how the parts fit together.
This step will assist you in reassembling the machine neat and orderly, preventing you from becoming frustrated due to misplaced tiny screws and components.
When Do You Need To Clean Lawnmower Air Filters?
To determine whether your air filter needs cleaning or replacement before you start, you must know how to do it. When it comes to paper filters, the simplest approach to determine whether it needs cleaning is to take it from the lawnmower, tap it lightly against a wall or floor to dislodge the dirt, and then carefully examine it in excellent lighting.
It’s time to change your filter if the majority of light is still obstructed even after you’ve tapped the dirt off it. Ensure the filter you buy and install is the right one by consulting your user handbook. Look for yellow spots and foam that have begun to crumble on the foam filter. Install a new filter if one of these can be found.
