So, what can you do now? I think you assume something. Yes, cleaning an air filter can save your engine from this hassle.
But have you any idea about how to clean a lawn mower air filter? If don’t, will you leave your air filter uncleaned? No way.

Guidelines On Cleaning An Air Filter Of Lawnmower

You know regular maintenance can keep the air filter in good condition. In fact, it is always recommended to clean the air filter after 25 hours of operating the lawnmower. And you should replace the air filter after 300 hours of operating the lawnmower.
A clean air filter increases the performance of the engine and a dirty one deteriorates the engine’s performance. If your lawn is full of dirt and debris, you need to be more careful about the maintenance of the air filter.
Before going to the main cleaning process, let’s know how many types of air filter is used in the lawnmower.
Basically, there are two types of air filters used in the lawnmower. One is the foam air filter and the other is the dual air filter.
In this article, you are going to get all the solutions about the cleaning process of both filters.
Foam Air Filter Cleaning Process
Even the foam air filter comes in two types. The first one is the disposable air filter and the reusable air filter is the second one.
Now, before we start cleaning, we need some necessary tools and materials to complete the task. Let’s have a look at them.
Necessary items
- A liquid soap to clean the grease from the air filters.
- A paper towel to wipe.
- Motor oil.
- Water.
- A cleaning brush.
After Getting All The Required Tools And Materials, Let’s Dive Into The Cleaning Process In Detail.

I hope from this article you have got a clear idea of how to clean a lawn mower air filter. Now it’s your turn.
Clean the air filter, increase the durability of the mower, and enjoy your leisure time by mowing.
Based upon one incredibly lousy experience, I would never purchase or use any Snapper product.
I have the grim misfortune of owning a Snapper lawn mower which my future wife purchased new from a dealer in 2016. The model # is 12ALC3B3707 per a label on the mower chassis and 1696628 per the owner’s manual that came with the mower.
Said product is a total piece of crap. If OSHA and the EPA possessed any level of competence, they would order a recall of this product.
The mower has one good feature – the single lever mechanism to raise and lower the mower deck. This one feature is far outweighed by many its worthless features, among which are:
(1) The design of the grasscatcher attachment to the mower is unacceptably poor. During operation, the grasscatcher frequently falls off and becomes a tripping hazard.
NOTE: I mitigated this defect by installing a chain on the catcher and a knob on the rear discharge door (RDD). This work around is an annoyance to use but is better than the risk of injury.
(2) When “properly” mounted, there is a 1” gap between the catcher and the RDD. During the brief period that the grasscatcher remains attached to the mower, the mower throws a continuous stream of clippings and dust into the face of the operator.
NOTE: I mitigated this defect by mounting a shield on the catcher bonnet. Like the chain, this work around is an annoyance to use but is better than the risk of eye or lung injury.
(3) The mower leaves a substantial trail of clippings in its wake even when the grasscatcher bag is empty. The mower leaves more clippings than it collects after the bag is a third to half full. My old Toro is much better.
(4) The automatic start feature is a joke. One must leave it on the charger overnight to get one decent start. If the mower should stall during operation, forget autostart. One must use the pull cord.
(5) The self-propulsion feature is unacceptably poor both in terms of operation and reliability.
a. The various settings appear to regulate torque to the wheels rather than speed – to wit, a higher setting is required to provide any assistance at all on even the gentlest upward slope. On the same setting the mower takes off like a bat out of hell on level ground or on a gentle downward slope.
b. The self-propulsion feature requires frequent servicing. The lower “speed” settings essentially stop working after 3 or 4 lawn mowings.
It is no mystery to me that there are so many lawn equipment dealers in Iowa who formerly sold Snapper products but no longer do so.
