6 Pack 593260 798452 334404 Lawn Mower Air Filter Replacement for Briggs and Stratton 500/500ex/550ex/625e/675ex/675exi/725exi Series Engines, Compatible with Troy Bilt TB110 TB200 TB230 Lawn Mowers

What It Is

This 6-pack of air filters replaces OEM part numbers 593260, 798452, and 334404, designed for Briggs & Stratton 500, 500EX, 550EX, 625E, 675EX, 675EXI, and 725EXI series engines. It’s a direct-fit foam pre-filter and paper cartridge combo for push mowers, riding mowers, and tractors using those engines—common on Troy-Bilt TB110, TB200, and TB230 models.

Fitment & Compatibility

Before buying, confirm your engine model number (stamped on the valve cover or blower housing) matches the 500–725EXI series. Check your existing filter dimensions: the foam pre-filter should be roughly 2.5” x 1.5” x 0.75”, and the paper cartridge about 3.5” x 2.5” x 1.5”. This set is aftermarket, not OEM Briggs & Stratton, but fits the same air box. It will not fit Intek, Vanguard, or single-cylinder OHV engines with a different air filter housing. Verify your mower brand and deck size (e.g., 20”–22” push mowers) aren’t a guarantee—engine series is the key.

Key Things to Know

• Quality vs OEM: Users report comparable filtration to original parts, but the foam may be slightly less dense. Fine for standard grass cutting; consider OEM for heavy dust or fine debris.
• Installation: Takes under 5 minutes. Remove the air filter cover (usually a wing nut or clip), swap out the old foam and paper elements, and reinstall. No tools needed.
• Common Gotcha: The 6-pack means you’ll have spares—store in a dry place. Some users note the foam pre-filter may need a light oiling (use air filter oil) for best performance; it’s dry out of the pack.
• Frequency: Replace every 25 hours of use or once per season, whichever comes first. Check monthly in dusty conditions.

Should You Buy It

If you own a Briggs & Stratton 500–725EXI engine mower (especially Troy-Bilt TB110/TB200/TB230) and want a cost-effective, easy-to-install filter supply for multiple seasons, this 6-pack is a solid value. It’s not for heavy-duty or commercial use, but for typical residential mowing, it’ll keep your engine breathing clean without breaking the bank.
