6 Best Mower Air Filters For Craftsman Mowers That Extend Engine Life
Choosing the right air filter is key to your Craftsman mower’s health. Discover our top 6 picks designed to protect and extend your engine’s life.
You’re halfway through mowing the back pasture when the engine on your trusty Craftsman starts to sputter and lose power. It’s a familiar, frustrating feeling that can derail a whole afternoon of work. More often than not, the culprit isn’t a complex mechanical failure, but a simple, overlooked part: a clogged air filter.

Protecting Your Craftsman Engine with Air Filters
An air filter is your engine’s first line of defense. It stops the dust, dirt, and grass clippings kicked up during mowing from getting sucked into the carburetor and engine cylinder. Think of it as the lungs of your mower; if it can’t breathe, it can’t work.
When a filter gets clogged, the engine is starved for air. This forces it to run "rich," meaning it burns more fuel than it should, fouling the spark plug and leaving carbon deposits inside the engine. Over time, this leads to poor performance, hard starting, and eventually, permanent damage.
For a hobby farmer, a reliable mower isn’t a luxury, it’s a core tool. A ten-dollar filter is the cheapest insurance you can buy against a thousand-dollar engine replacement. Whether you choose an original equipment manufacturer (OEM) part or a quality aftermarket alternative, the key is to replace it before it becomes a problem.
Briggs & Stratton 593260: The OEM Standard
For the countless Craftsman mowers powered by a Briggs & Stratton engine, this is the gold standard. The 593260 is the OEM part, meaning it’s made by the same company that built your engine. There’s no guesswork about fit or quality.
The primary advantage here is peace of mind. You know it’s designed to meet the exact airflow and filtration specifications your engine requires for optimal performance and longevity. The pleats are uniform, the sealing gasket is precise, and the materials are built to last through a tough season.
The tradeoff, of course, is cost. OEM parts almost always carry a premium price tag compared to their aftermarket counterparts. If your mower is still under warranty or you simply don’t want to risk compatibility issues, spending a few extra dollars on the Briggs & Stratton original is a wise investment.
Stens 102-012: Top Aftermarket Performer
Not all aftermarket parts are created equal, and Stens has earned a solid reputation for producing replacements that often meet or exceed OEM specifications. The Stens 102-012 is a direct replacement for the Briggs & Stratton 593260 and is a go-to for many who do their own maintenance. It offers a near-identical fit and filtration capacity.
The real draw is the balance of quality and price. You get a filter that performs reliably without the OEM markup. Stens parts are widely available and trusted in the small engine repair community, so you’re not taking a gamble on an unknown brand.
This is the right choice for the operator who understands their equipment and is comfortable stepping outside the OEM ecosystem to save some money. It delivers consistent performance for mowing pastures, clearing fence lines, and all the other demanding jobs on a small farm. It’s a workhorse filter for a workhorse machine.
Kohler 20 083 02-S: For Courage Series Engines
It’s crucial to remember that "Craftsman" is the brand of the mower, not the engine. Many larger Craftsman riding mowers and zero-turns are equipped with powerful Kohler engines, particularly from the Courage and 7000 Series. For these machines, the Kohler 20 083 02-S is the correct OEM filter.
This filter kit is designed specifically for the airflow needs of these larger twin-cylinder engines. It almost always includes a foam pre-filter, which is essential for the dusty, high-debris conditions often found on a farm or homestead. The pre-filter catches the larger particles, allowing the inner paper element to focus on trapping the fine dust that causes the most engine wear.
Never try to fit a Briggs & Stratton filter on a Kohler engine, or vice versa. They are not interchangeable. Always check your engine’s model number to ensure you’re buying the right part for the job. Using the wrong filter can starve the engine of air or fail to seal properly, rendering it useless.
Maxpower 334412: A Reliable, Affordable Option
Sometimes, good enough is exactly what you need. Maxpower specializes in producing affordable and widely available replacement parts, and their 334412 air filter is a solid, budget-friendly option for Briggs & Stratton engines. It gets the job done without fuss.
Is the paper media as dense or the pleat count as high as a premium OEM filter? Maybe not. But it’s a massive improvement over a dirty, clogged filter, and its low cost makes it easy to keep a few on hand.
This is the practical choice for someone who mows in less-than-brutal conditions or who prefers to swap out filters more frequently as a preventative measure. If you’d rather spend three dollars twice a season than ten dollars once, the Maxpower filter makes perfect sense. It prioritizes function over brand prestige.
Husqvarna 531307044: Durable Pleated Filter
For years, a huge number of Craftsman mowers were manufactured by American Yard Products (AYP), which is owned by Husqvarna. Because of this, many Husqvarna parts are identical to their Craftsman-branded counterparts and can be used interchangeably. The Husqvarna 531307044 is a high-quality filter that fits many of the same Briggs & Stratton engines as the other filters listed.
This filter is known for its durable construction and a large surface area of pleated paper. That design is excellent for trapping a high volume of dust and debris before it restricts airflow, making it a great option for late-summer mowing when the ground is dry and dusty.
Think of this as another trusted OEM-level choice. If your local shop is out of the Briggs & Stratton filter but has the Husqvarna equivalent on the shelf, you can buy it with confidence knowing it will fit and perform correctly. It broadens your options for finding a quality part when you need it.
8TEN 810-AFR2234T: Heavy-Duty Filter/Pre-Filter
For the toughest jobs, you need the best protection. The 8TEN filter and pre-filter combo is designed for dusty, demanding environments. This two-stage system is the ultimate defense for your engine when you’re mowing overgrown fields, mulching dry leaves, or working on a dirt driveway.
The outer foam pre-filter is your first line of defense. It captures coarse debris like grass clippings, chaff, and larger dust particles. This keeps the inner paper filter from clogging prematurely, allowing it to do its job of trapping the fine, abrasive dust that can score a cylinder wall.
This is more than just a replacement; it’s an upgrade. For a small additional cost, you get significantly longer service intervals and superior engine protection. If you rely on your mower to do more than just cut a suburban lawn, investing in a filter with a pre-filter is non-negotiable.
Installation and Maintenance for Peak Performance
Replacing an air filter is one of the easiest maintenance tasks you can perform. The filter is typically housed in a plastic or metal case on the side of the engine, held on by a single screw or a couple of clips. No special tools are needed—just pop the cover off, pull the old filter out, and seat the new one firmly in place.
The most important step is ensuring the new filter creates a perfect seal. Any gap will allow dirty air to bypass the filter and go straight into your engine. Before closing the cover, wipe out any dust or debris from inside the housing with a clean rag.
How often should you change it? Forget the owner’s manual recommendation of "every 100 hours." Your working conditions dictate the schedule. In a dry, dusty summer, you should be checking it after every couple of mows and replacing it as soon as it looks dirty. In the damp spring, you can go much longer. A visual inspection takes 30 seconds and tells you everything you need to know.
Ultimately, the best air filter brand is less important than the simple act of regular inspection and replacement. A cheap, clean filter will always protect your engine better than a premium, clogged one. Match the right filter to your engine model, consider your working conditions, and you’ll keep that Craftsman running strong for many more seasons.
