What It Is

This is a drop-in replacement air filter for small engines on walk-behind lawn mowers, specifically compatible with Briggs & Stratton engines in the 500–700 series (e.g., 5432, 550ex, 675ex, 725exi) and certain Troy-Bilt models (TB110, TB200, TB230). It replaces OEM part numbers 593260, 798452, and 334404.

Fitment & Compatibility

Before buying, check two things:

1. Engine model number – This filter fits B&S engines with series numbers 5432, 5432K, 550ex, 675ex, and 725exi. It also fits Troy-Bilt mowers TB110, TB200, and TB230. It does not fit all B&S engines—verify your engine’s model number (stamped on the valve cover or near the spark plug).
2. Physical dimensions – The filter is roughly 4.5 x 3 x 1.5 inches with a rectangular foam-and-paper element. Measure your old filter or the air cleaner housing opening to confirm it matches.
3. OEM vs aftermarket – This is an aftermarket part, not genuine Briggs & Stratton. It’s a direct swap for OEM 593260, 798452, and 334404 but may have slightly different foam density or paper pleating. It should seal properly if the housing is clean and undamaged.

Key Things to Know

• Installation is tool-free – Remove the air cleaner cover, pull out the old filter, drop in the new one, and snap the cover back on. No screws or clamps.
• Inspect the housing seal – If the foam gasket around the filter edge is crushed or the housing has cracks, the filter won’t seal, and dirty air will bypass it. Replace the housing if needed.
• Pre-oil the foam – Some aftermarket filters come dry. Lightly coat the foam section with engine oil (or filter oil) before installation to improve dust capture. Squeeze out excess—don’t soak it.
• Check for debris – If your mower ran with a torn or missing filter, check the carburetor throat for dirt before installing the new one. A clogged carb can cause hard starting or rough running even with a clean filter.

Should You Buy It

Yes, if you need a budget-friendly replacement for a compatible B&S or Troy-Bilt mower and don’t mind an aftermarket part. The 4.8-star rating and low price make it a solid value for routine maintenance. Avoid it if you prefer genuine OEM parts or if your engine model isn’t listed—fitment is narrow.
