A lawn mower must be well maintained to be continually functional. Different parts of the lawn mower could impact its performance if they are not taken care of. It could be a simple component like the air filter which traps a lot of dirt and dust as the mower operates.
Dirt that clogs up the air filter in the lawn mower could block the proper flow of air to the carburetor; the cooling surfaces of the mower are blocked to cause the engine to overheat. Hence, the lawn mower requires a clear and clean air filter to keep the air coming through for an efficient engine.
The user manual of the lawn mower usually lists specific instructions on handling and maintaining the machine. This would include regular cleaning of the mower engine as part of the recommended cleaning schedule regardless of mower model, brand, or size. There are specific steps that are listed in the user manual for cleaning the mower’s air filter. This could include the pre-cleaner and cooling areas besides the air filter piece.

The basic recommended cleaning instructions listed in most mower manuals include cleaning the air filter paper after every two or three mowing sessions. The foam pre-filter needs to be washed every 25 hours of application.
1) Filter cover
The first step in cleaning out the mower air filter thoroughly is to remove the cover of the filter. This is a critical activity to ensure continual efficiency on the mower. This cleaning process should be executed in a clean work area where there is less likelihood of dirt or dust blowing especially into the lawn mower.
A simple wiping off the debris or loose dirt near the cover of the air filter is preferred to avoid dirt or debris from falling into the engine. The wing nuts of the cover should be removed carefully and put aside safely for reinstallation. These nuts are important components which keep the cover in its place for a proper functioning of the air filter.
2) Foam Pre-filter
There are various parts to the lawn mower which must be cleaned properly. Before the air filter is removed, its surroundings like the rubber seal should be wiped clean using a moist clean rag. This action must be carefully performed to avoid pushing dirt into the air filter internal.
The mower air filter must be carefully removed without damaging. If there is a foam pre-filter present in the mower, it should also be removed. These components of the mower must be properly cleaned when the mower has been used for 25 hours; alternatively, the mower should be cleansed at least once a year. This is the basic guideline in keeping the mower and its air filter checked to be efficient. Either condition applies for an effective and functional mower where the mower’s foam pre-filter should be soaked thoroughly in a diluted dish detergent liquid.
There is no need to scrub the foam pre-filter as time in the liquid dish detergent would ease out the attached dirt and grime. Just pat the foam pre-filter dry gently with a paper towel to soak up the water. A clean rag could also be used without damaging the foam piece.
If such soaking does not remove the dirt or grime effectively or the foam becomes damaged in the process, it is advisable to replace the foam pre-filter as a damaged piece is non-functional. There may be too much grime attached to the foam pre-filter which could not be released.
The foam pre-filter is an essential part of the mower which helps to act as an extra protection for the air filter. However, not every mower has this feature. Having the foam pre-filter helps lengthen the durability of the paper air filter.
3) Paper Filter
Another piece of mower part is the paper filter. It must be cleaned to ensure greater efficiency by the mower. The paper filter should be tapped gently by hand on a flat surface to loosen the accumulated dirt and dust.
Care must be exercised in tapping the paper filter which is quite flimsy and tears easily with too much force. A torn or ripped filter is not of much use in the mower as it would not be able to trap the dirt and dust flowing through. Hence, it should be replaced immediately; otherwise, the dirt and dust, as well as small pieces of stones or grass, could flow right into the mower engine and internal parts to cause greater damage.
Users are warned not to apply compressed air or any form of petroleum products to clean the air filter paper. Petroleum-based products such as oil, kerosene, and gasoline are highly abrasive to cause damage to the filter which is made of paper.
The Installation Process
The mower filter and cover are important components in the mowing device. Once the air filter pieces are thoroughly cleaned including the rubber seal surfaces, they could be put back into the proper position and the wing nuts must be tightened.
This would ensure that the air filter is rightly positioned for its effective function. The air filter cover should also be placed properly at its original location with the wing nuts securing it aptly. However, the cover should not be over tightened to avoid tension and potential damage.
Necessity of Cleaning
An air cleaner that is well maintained to be in constant good condition works to keep airborne particles of dirt and dust at bay. It is very effective in keeping the carburetor clean as dirty air is filtered from entering.It is crucial to maintain the mower air filter which is also known as the air cleaner. This piece of component is the first line of defense for the mower engine against dirt and grime with its destructive effects.
Without a clean air filter, dirt, dust and small particles could find their way to the engine and clog it. Any amount of dirt could damage the various parts of the mower or cause a drastic decrease in the power of the mower engine. Hence, the mower could experience premature wear and tear with its various engine components.
The market offers different types of air filters in different types of lawn mowers in various brands and models. A lot of mowers use air filters in their small engines which include foam filters or a pleated paper filter.
There are dual-element cleaner mowers where the cleaning elements comprise the foam pre-cleaner and a pleated paper filter. Such feature offers a double layer of protection for the engine in case of stubborn and tough grime or dirt from grass or soil. When the paper element becomes highly soiled, it is no longer functional or effective. Dirt would not be kept out from the carburetor or engine. This is obvious when the dirt clings tightly to the paper filter even when tapped on a hard surface.
Cleaning the foam pre-filter could wash out the stubborn layer of dirt and grime if hot water is applied with a strong yet gentle liquid dish detergent containing grease-cutting agent. A dual-element or double featured air cleaner is available in various designed.
