2 Pcs 593260 Lawn Mower Air Filter 798452 334404 Replace for 500 500ex 550ex 625e 675ex 675exi 725exi Series Engines Models, Compatible with Troy Bilt TB110 TB200 TB230

What It Is

This is a two-pack of replacement air filters designed for small-engine lawn mowers, specifically those powered by Briggs & Stratton 500, 500ex, 550ex, 625e, 675ex, 675exi, and 725exi series engines. It also fits Troy-Bilt models like the TB110, TB200, and TB230. The filter keeps dirt and debris out of the carburetor and cylinder, ensuring clean airflow for proper combustion.

Fitment & Compatibility

Before buying, confirm your engine’s model number (e.g., 500ex, 675exi) – not just the mower’s brand or deck size. These filters replace OEM part numbers 593260, 798452, and 334404. Physically measure your old filter: this one is roughly 3.5 x 2.5 x 0.75 inches, with a rectangular foam-and-paper construction. It will not fit engines with round or cylindrical filter housings (common on some Honda or Kohler engines). Cross-check your mower’s manual or existing filter’s part number before ordering.

Key Things to Know

• Quality: Aftermarket foam and paper construction. 5.0-star rating from 18 reviews suggests good consistency, but may be slightly less dense than OEM – fine for residential use.
• Installation: Tool-free – just remove the cover, swap the old filter, and re-secure. Takes under 2 minutes.
• Common gotcha: Some Troy-Bilt models (e.g., TB230 with a Briggs 725exi) use this filter, but older TB200 variants may require a different shape – always verify by engine model, not mower model.
• Two-pack value: At $5.99, you get two filters – roughly half the price of a single OEM filter. Replace every 25 hours or once per season.

Should You Buy It

If you own a Briggs & Stratton 500–725exi series engine or a compatible Troy-Bilt mower, this is a solid, low-cost maintenance buy. The two-pack gives you a spare, installation is dead simple, and the price is hard to beat for routine upkeep. Skip it if you need a round filter or have a non-Briggs engine.
