593260 Air Filter, 798452 334404 Lawn Mower Air Filter for Briggs and Stratton 550ex 675exi 725exi Series, for Troy Bilt TB110 TB200 TB230 Lawnmower and More(6 Pack)

What It Is

This is a 6-pack of aftermarket air filters designed to replace OEM part numbers 593260, 798452, and 334404. It fits Briggs & Stratton engines like the 550ex, 675exi, and 725exi series, commonly used on Troy-Bilt TB110, TB200, and TB230 walk-behind mowers, plus many other push mowers with compatible engines.

Fitment & Compatibility

Before buying, confirm your engine model (e.g., 550ex, 675exi) and check the air filter housing shape. These filters are rectangular with a foam pre-cleaner layer, measuring roughly 3.5" x 2.5" x 1". They are direct aftermarket replacements for OEM Briggs & Stratton filters—not a universal fit. Verify your mower’s deck size (e.g., 21-inch, 22-inch) is irrelevant; only the engine model matters. Cross-reference your old filter’s part number or measure your current filter’s dimensions. Avoid assuming fitment for non-Briggs engines like Kohler or Honda.

Key Things to Know

• Quality: These are foam-and-paper composite filters. They work well for regular mowing but may not match OEM longevity in heavy dust or fine grass clippings. Replace every 25–50 hours or when visibly dirty.
• Installation: Extremely simple—remove the air filter cover, swap the old filter, and reattach. No tools needed. Ensure the filter sits flat and the cover seals properly to prevent debris bypass.
• Common gotcha: The foam pre-cleaner can detach from the paper element if handled roughly. Gently press it back in place before installing. Also, some users report a slightly looser fit than OEM—check that the cover snaps tight.
• Value: Six filters for ~$18 is a solid deal compared to buying singles at big-box stores. Stock up for multiple seasons or multiple mowers.

Should You Buy It

If you have a compatible Briggs & Stratton engine (550ex, 675exi, 725exi) and want a low-cost, no-fuss supply of replacement filters, this 6-pack is a smart buy. It’s ideal for routine maintenance on one or two mowers. However, if you mow in extremely dusty conditions or prefer OEM-certified parts for warranty reasons, stick with a single Briggs-branded filter.
