10 Pack 593260 Lawn Mower Air Filter 798452 334404 Replacement, Fit for Most 500 500ex 550ex 625e 675ex 675exi 725exi Series Engines Models, Compatible with Troy Bilt TB110 TB200 TB230 Lawnmower.

What It Is

This is a 10-pack of replacement air filters (cross-reference OEM #593260, 798452, 334404) designed for small engines—primarily Briggs & Stratton 500, 500ex, 550ex, 625e, 675ex, 675exi, and 725exi series. Ideal for walk-behind mowers, these filters keep dust and debris out of your carburetor, ensuring cleaner combustion and longer engine life.

Fitment & Compatibility

• Engine series only: Fits Briggs & Stratton 500–725exi single-cylinder engines. Does NOT fit Vanguard, Intek, or OHV series.
• Lawn mower brands: Compatible with Troy-Bilt TB110, TB200, TB230—and many MTD, Craftsman, Cub Cadet, and Husqvarna models using those engines.
• Before buying: Check your engine model number (stamped on the blower housing or valve cover). Confirm it starts with 12, 1A, 1B, 1C, 21, 2A, 2B, 2C (Briggs 500–725 series). Measure the filter: roughly 2.5” x 2.5” x 1” (the foam pre-filter is separate; this is the paper element).
• Cross-reference: Also replaces OEM 593260, 798452, 334404. If your mower uses a different filter shape (e.g., round or larger rectangular), this won’t fit.

Key Things to Know

• Quality: Dense paper media with a foam pre-filter layer. Users report it’s comparable to OEM—filters fine dust well. No off-gassing or fitment issues in most cases.
• Installation: Tool-free. Remove the air filter cover (usually a single screw or clip), swap the old filter, and reinstall. No oiling needed (this is dry paper, not foam).
• Common gotcha: Some users note the foam pre-filter can slip off the paper element if not seated fully. Press it down firmly before inserting.
• 10-pack value: At $2 per filter, it’s cheap enough to change every 25 hours of use or each season—great for multiple mowers or frequent replacements.

Should You Buy It

If you own a Briggs 500–725 series mower (Troy-Bilt TB110/TB200/TB230, etc.) and want a reliable, low-cost way to keep the engine breathing clean, this pack is a solid buy. The fitment is correct for most common small engines, and the 10-pack means you’ll have spares for years. Skip it if your engine uses a different filter shape or if you need a foam-only filter.
