Air Cleaners Parts
7 products available
The air cleaner is the small engine's only defense against the dust and grit a jobsite throws at it, and on a gas pressure washer it sits directly ahead of the carburetor — a torn or clogged element lets abrasive dirt straight into the cylinder. Most small engines on pressure washers (Honda GX and GC series, Briggs & Stratton Vanguard) use a foam pre-filter over a paper element, housed under a wing-nut-secured cover, and both the element and the wing nut are wear items sold separately.

Air Cleaners Buying Guide
Match the element to the engine model
Air cleaner assemblies and replacement elements are sized to a specific engine family — GX160-200, GX240-270, GX340-390, and Briggs Vanguard each use their own housing and element. Cross-reference your engine's model/spec number (stamped on the shroud) against the listing before ordering; a close-looking element from a different engine family often won't seal correctly.
Foam pre-filter + paper element, both replaceable
The foam pre-filter is the first stage and takes the brunt of coarse dust; it can be washed in mild detergent, dried, and lightly oiled per the engine manufacturer's service manual. The paper element behind it catches fine particles and should be replaced, not washed — compressed air or water breaks down the paper's filtering ability even when it looks intact.
A dirty filter costs more than the part
A clogged air cleaner starves the engine of air, which richens the fuel mixture, fouls the spark plug, and can lead to carbon buildup or reduced compression over time. Given the low cost of the element versus the cost of top-end engine work, most manufacturers recommend replacing the paper element well before it looks fully blocked — check it every 25 hours of use in dusty conditions.
Air Cleaners FAQ
How do I know which air cleaner fits my engine?
Match it to your engine's model and spec number, not just the horsepower — Honda's GX160-200, GX240-270, and GX340-390 families each use a different air cleaner assembly, and Briggs Vanguard engines use their own housing entirely. The number is stamped on the engine shroud near the air cleaner cover.
Can I wash and reuse the paper element?
No — only the foam pre-filter is washable. The paper element is a one-time-use part; washing or compressed-air cleaning damages the paper's pore structure even when no damage is visible, so replace it instead.
What happens if I run the engine with the air cleaner cover off?
Unfiltered dust and grit reach the carburetor and cylinder directly, accelerating wear and risking a lean-running condition. Never run the engine without the element and cover installed, even briefly.
