(4-Pack) 593260 798452 334404 Lawn Mower Air Filter for 550ex 675exi 725exi Series fits Troy Bilt TB110 TB200 TB230 Lawnmower and More

What It Is

This is a 4-pack of replacement air filters (models 593260, 798452, 334404) designed for small-engine lawn mowers, specifically the Troy-Bilt TB110, TB200, TB230 series and other mowers using Briggs & Stratton 550ex, 675exi, and 725exi engines. It filters dirt and debris from intake air to protect the engine.

Fitment & Compatibility

• Check your engine model: This filter fits Briggs & Stratton 550ex, 675exi, and 725exi series engines. Look for a model number on the engine shroud (e.g., “12A-xxx” or “1xx-xxx”).
• Mower models confirmed: Troy-Bilt TB110, TB200, TB230. Also fits many Craftsman, Husqvarna, and MTD mowers with the same engines.
• OEM vs aftermarket: This is an aftermarket part, not OEM Troy-Bilt or Briggs & Stratton. It matches OEM numbers 593260, 798452, and 334404.
• Measurements: The filter is roughly 3.5" x 2.5" x 1.5". If your current filter matches these dimensions, it should fit.
• Deck size irrelevant: Deck size (e.g., 21" or 22") does not affect compatibility—only the engine model matters.

Key Things to Know

• Quality: Users report good fit and seal, but aftermarket foam may be slightly less dense than OEM. Inspect for proper seating to avoid unfiltered air.
• Installation: Easy—remove old filter, clean the housing, insert new filter, and close the cover. No tools needed.
• Common gotcha: Some mowers use a slightly different filter (e.g., 5090E or 793269). Double-check your existing filter’s part number before buying.
• Value: $9.99 for a 4-pack is a solid deal—OEM single filters often cost $6–10 each. Replace every season or after 25 hours of use.

Should You Buy It

Yes, if you own a Troy-Bilt TB110, TB200, or TB230 (or a mower with a 550ex/675exi/725exi engine) and want an affordable, reliable replacement. It’s not for older or different engine series, but for these common models, it’s a great value.
