Air Filters That Fit Craftsman Lawn Mowers

Craftsman lawn mowers have long been a staple in residential yard care, recognized for dependable cutting decks, sturdy steel frames, and small engines that handle tough grass through the spring and summer months. Maintaining the proper airflow on these machines is critical to keeping the fuel-and-air mixture balanced, protecting internal cylinders from abrasive dust, and preventing engine sputtering during heavy cutting sessions. Regular maintenance requires knowing your specific engine family, as walk-behind push units and large lawn tractors rely on completely different filtration shapes to trap debris.
While some options provide direct flat-panel replacements for classic engines, others arrive as full intake service bundles, protective outer housings with dual-stage media, dedicated cartridges for modern overhead-valve engines, or cylindrical filters built specifically for twin-cylinder lawn tractors.

The 2 Packs 491588S Air Filter pack by Haigelisi provides two replacement flat-panel elements engineered to match standard small-engine air boxes. Sized at 5.2 inches in length, 4.5 inches in width, and 0.8 inches in height, this cartridge is designed to match OEM standards for walk-behind units. The listing notes fitment for Craftsman 3364 mowers alongside 3.5 to 6.75 horsepower Quantum small engines, including the 625, 675, 725, and 625-675e/ex series. It also lists compatibility with Toro walk-behind models such as 20332, 20334, and 20330, as well as selected Troy-Bilt and Honda small equipment.
In terms of materials, the manufacturer highlights soft sealing gaskets crafted with less rubber glitter to produce a cleaner, tighter seat against the intake housing. The pleated design supplies a larger filtration area than standard base elements, supporting higher air intake and smoother engine breathing to maintain fuel consumption during mowing cycles. If you have an older walk-behind machine equipped with a Quantum small engine, selecting a proper briggs and stratton air filter equivalent is vital to keeping debris out of the carburetor throat. The two filters are individually packaged, making it convenient to store one on the shelf as a backup for mid-season tune-ups.
This two-pack suits homeowners operating classic walk-behind push or self-propelled mowers who want a multi-pack replacement for standard maintenance. It provides an immediate refresh for flat-intake filter boxes without extra hardware or unnecessary assembly. However, because it carries no manufacturer warranty and is strictly a flat rectangle cartridge, it gives way to broader tune-up kits or custom-molded covers if your intake box requires structural repairs or complete fuel-system maintenance.

- Full carburetor and filter bundle

- Backed by 1-year warranty
- Solves hard-starting issues
Cons
- Unneeded parts for basic filter swaps
When an engine struggles to draw fuel or runs unevenly after sitting through winter storage, simply replacing the paper element may not resolve the issue. The M110 Carburetor Air Filter for Craftsman by Toobop addresses broader operational issues by packaging an intake filter together with a full fuel-system overhaul setup. Designed for walk-behind mowers driven by 140cc, 150cc, and 190cc small engines, this kit lists compatibility with Craftsman M110, M220, M230, and M400 walk-behind machines corresponding to carb reference 11A-A2T2793.
Rather than including only the pleated filter element, this set includes one high-performance carburetor, one mounting gasket, a flexible fuel line, one air cleaner filter, a replacement spark plug, and two tension hose clamps. Toobop notes that the comprehensive assembly optimizes engine efficiency by restoring smooth fuel delivery, lowering rough emissions, and extending overall machine operational life. The components are manufactured from durable materials built to withstand heat and vibration under rigorous summer cutting demands.
This kit is the ideal choice for lawn owners who are facing rough idling, fuel varnish, or hard-start problems alongside a dirty intake filter. Instead of sourcing multiple maintenance parts separately, this package provides everything needed to refresh spark, air, and fuel intake in one project. For gardeners who only need a routine paper filter swap and already have a clean carburetor, this package introduces excess parts and gives way to standalone replacement cartridges.

Pros
- Includes plastic replacement cover
- Comes with protective pre-filter
- Backed by 1-year warranty
- Direct fit for 140cc M110
Cons
- Only fits 140cc M110 models
Mower air cleaner assemblies endure substantial physical stress from flying gravel, vibrating engine brackets, and accidental brush strikes. The Air Filter Cover with Filter set by znakeauto is designed specifically for owners of the 140cc Craftsman M110 walk-behind mower who need to restore damaged exterior housing parts while replacing the filtration media. This three-piece kit contains one replacement outer air cleaner cover, one main paper air filter element, and one dedicated pre-filter wrap.
The pre-filter fits securely around the primary pleated filter to capture coarse grass clippings and loose dirt before fine airborne dust reaches the inner paper pleats, extending the operational life of the primary paper cartridge. znakeauto lists the kit as an easy-to-install, direct-fit replacement for the M110 assembly, backed by a 1-year manufacturer warranty. Having a fresh outer cover ensures the intake cavity remains sealed against moisture and engine heat, preventing dirty air from bypassing the filter perimeter on your craftsman push mower.
This configuration suits operators who have broken plastic latches, cracked air box lids, or lost their factory housing during seasonal cleaning. It restores both the intake shroud and filtration assembly in a single step. However, if your existing plastic filter housing is completely intact and you only need clean paper media, purchasing an entire cover assembly is redundant, making standalone filter packs a more focused choice.

Air Cleaner Filter for Craftsman M140 for 160cc Walk-Behind Engines
8.8/10 Our score
Best for: Routine maintenance on 160cc M140 mowers
What the listing says
- Air Cleaner Filter Compatible with Craftsman M140 160cc CMXGMAM1125500 Lawn Mower.
- Perfect OEM fit, seamless synergy with your engines.
- High-density porous structure, ultra-efficient dust & debris filtration for engine protection.
- Industrial-grade durability for long-term use.
- Package Included 1 Air Filter.
Pros
- High-density porous structure
- Exact OEM fit for CMXGMAM1125500
- Industrial-grade durability
- Backed by 1-year warranty
Cons
- Single filter pack
- Specific to 160cc M140 housing
The Air Cleaner Filter for Craftsman M140 by Muawica is tailored for the Craftsman M140 160cc walk-behind mower, carrying direct reference to part number CMXGMAM1125500. Small engines displacing 160cc require consistent air volume to generate adequate blade torque in tall grass, making a clean, porous intake boundary essential for engine performance. This single replacement part is produced to meet OEM fit standards, seating securely into the engine intake housing without modification.
Muawica emphasizes an industrial-grade, high-density porous structure that traps fine dust, grit, and debris while allowing steady airflow directly into the carburetor throat. The durable construction resists degradation from heat cycles and intake moisture during humid summer yard work. The listing references model MW2615 and part number M140160cc, backed by a 1-year manufacturer warranty for added confidence during seasonal prep.
This air filter fits property owners who maintain a Craftsman M140 160cc mower and want a simple, exact-match cartridge to prepare their equipment for the mowing season. It ensures that the engine retains steady power without risking unmetered air leaks. However, because it is custom-molded to 160cc M140 housings, it gives way to the smaller M110 components or large riding tractor canisters if you manage a different deck configuration.

- Heavy-duty cylindrical core
- Direct replacement for 796031
Cons
- Short 2-week DOA warranty
- Will not fit push mowers
Lawn tractors and large riding mowers require substantially larger air cleaners than compact walk-behind units due to their high-displacement vertical shaft and V-twin engines. The HQRP Filter compatible with Husqvarna YTA22V46 provides a heavy-duty cylindrical cartridge designed for riding lawn tractors. Sized at 5 inches in height, 3 inches in outer diameter, and 1-5/8 inches in inner diameter, this cylindrical filter includes both the primary pleated core and an outer foam pre-filter wrap.
The listing confirms fitment across Craftsman IT1500 and IT2000 riding tractors, along with Husqvarna YTA22V46, YTH22V46, YTH24V48, GTH52XLS, HU800AWD, and Poulan-Pro PB22VA48 models. It serves as a direct replacement for small-engine part numbers 796031, 797704, 5421, 590825, 591334, and 594201. Engineered for number 31 vertical shaft engines ranging from 13.5 to 19.5 horsepower and Intek V-Twin engines spanning 16 to 24 horsepower, it filters heavy soil and fine chaff churned up by large multi-blade mower decks. The product includes a 2-week DOA replacement warranty.
This cylindrical cartridge is ideal for homeowners maintaining Craftsman IT-series riding lawn tractors with high-horsepower engines. Its two-stage filtration handles heavy dust clouds that typically accumulate over large acreage. Because of its large round shape and central inner diameter, it cannot be mounted inside the compact rectangular filter boxes found on walk-behind push mowers.

- Package Includes 2x Air Filter Compatible with 21"""" Craftsman M250
Pros
- Two filters in package
- Exact match for 12A-469Q799
- Backed by 1-year warranty
- Convenient spare for mid-season
Cons
- Does not include pre-filter
- Model specific to M250 series
The 2x Air Filter Compatible with 21″” pack from znakeauto offers two replacement elements matched to 21-inch Craftsman M250 walk-behind lawn mowers. Sourced under model reference Air Filter 21″ Craftsman M250 and OEM equivalent 12A-469Q799, this dual pack targets machines carrying model designations CMXGMAM1125503, 247.379000, and 247.37683 (also formatted as 247379000, 24737683, and 12A469Q799).
These filters are fabricated to match the precise internal dimensions of the M250 air cleaner casing, preventing dirt from slipping around the sealing edge into the intake passage. znakeauto supplies two matching units in a single package, giving owners an immediate replacement alongside a spare element to swap in when cutting dusty turf or dry leaves later in the season. The filters are supported by a 1-year manufacturer warranty covering replacement defects.
This set suits users operating a Craftsman M250 21-inch mower who want a multi-pack dedicated specifically to their mower model series. It eliminates guesswork when matching Sears and Craftsman model cross-references like 247.379000. For owners of 140cc M110 or 160cc M140 machines, however, this cartridge will not provide the correct housing geometry and gives way to the model-specific options detailed earlier.
Before you choose
How to Choose the Right Craftsman Lawn Mower Air Filters
Finding the right air cleaner requires verifying your lawn mower model number, engine displacement, and filter enclosure style before purchasing. Craftsman walk-behind mowers span several equipment generations, each utilizing distinct air box dimensions. The popular M-series walk-behind line uses different filters depending on engine size: the M110 typically houses a 140cc engine, the M140 relies on a 160cc power plant, and the M250 utilizes specific 21-inch deck engine configurations. Checking the stamped model sticker under the mower deck or near the rear discharge chute guarantees an accurate match.
Physical shape is the fastest visual cue when sorting through replacements. Classic walk-behind engines commonly accept flat rectangular panels like the 2 Packs 491588S Air Filter, which measures 5.2 by 4.5 inches. In contrast, riding tractors like the Craftsman IT1500 and IT2000 require cylindrical filter cartridges such as the HQRP Filter compatible with Husqvarna YTA22V46, which features a central 1-5/8-inch mounting hole to slide over vertical-shaft intake spindles. Never attempt to compress a flat filter into a curved cavity or install a filter that leaves gaps along the sealing perimeter.
Assessing the overall condition of your intake assembly will also determine whether you need a standalone filter, a dual-stage kit, or a full intake overhaul. When the air filter base and latch are undamaged, standalone elements like the Air Cleaner Filter for Craftsman M140 or the 2x Air Filter Compatible with 21″” keep maintenance straightforward. If your machine suffered impact damage or cracked latches, the Air Filter Cover with Filter provides the necessary replacement cover along with an outer pre-filter. While tuning up the engine intake, inspecting related wear components like a fresh craftsman lawn mower blade ensures your machine cuts cleanly and runs efficiently all season long.
If your mower has sat unattended with stale fuel, replacing only the air filter might leave the engine surging or failing to start. In that scenario, comprehensive bundles like the M110 Carburetor Air Filter for Craftsman supply a new carburetor, fuel line, spark plug, and air cleaner in one package, solving intake flow and fuel delivery problems together.
Questions people ask
FAQ
How often should an air filter be replaced on a Craftsman lawn mower?
Most small-engine manufacturers recommend inspecting the air cleaner every 25 hours of operation or at least once per mowing season. In dry, dusty cutting conditions, dirt accumulates quickly, requiring replacement every few months to ensure adequate engine airflow and prevent premature cylinder wear.
Can a dirty lawn mower air filter cause starting problems?
Yes, a clogged air cleaner restricts the volume of fresh air reaching the carburetor, resulting in an overly rich fuel mixture. This imbalance can foul the spark plug, cause rough idling, produce black exhaust smoke, or prevent the small engine from starting altogether.
What is the benefit of using an air filter with a pre-filter?
A foam pre-filter wraps around the exterior of the primary paper cartridge to catch large grass fragments, chaff, and heavy dirt before they reach the fine paper pleats. This dual-stage setup extends the operating life of the paper filter and prevents the primary pleats from clogging prematurely during heavy mowing.
Are Craftsman push mower filters interchangeable with riding mower filters?
No, walk-behind push mowers and riding lawn tractors use fundamentally different filter designs. Push mowers rely on compact flat or low-profile rectangular cartridges, whereas riding mowers with 13.5 to 24 horsepower engines require tall cylindrical cartridges with hollow center openings to accommodate high-volume air intake.
How do I confirm which replacement filter fits my specific Craftsman mower?
Locate the model sticker on your mower frame or the engine data plate stamped into the metal blower housing. Match the model number, such as M110, M140, M250, or tractor series like IT2000, against the listing specifications and OEM part numbers to ensure complete compatibility.
