593260 Air Filter for Lawn Mower, 798452 334404 Replacement Air Filter Compatible with Toro Series Engine 550E 500EX 550EX 625 575EX 4247 5432 5432k, 4 Packs

What It Is

This is a 4-pack of replacement air filters (model 593260) designed for Toro gas lawn mowers with Series 550E, 500EX, 550EX, 625, and 575EX engines. It keeps dirt and debris out of the carburetor and engine for cleaner combustion and longer engine life.

Fitment & Compatibility

• Direct OEM replacements for Toro part numbers 593260, 798452, and 334404.
• Fits Toro models: 4247, 5432, 5432k, and all mowers with the 500/550/575/625 engine series listed above.
• Check your engine model (not just mower model) – this filter only fits Toro engines with a rectangular, foam-style air filter housing. Measure your old filter: it should be roughly 3.5" x 2.5" x 0.6".
• Does not fit Kawasaki, Briggs & Stratton, or Honda engines, or Toro models with a round or cylindrical filter.
• Aftermarket (non-OEM) – quality is high per reviews, but fitment may be slightly tighter than genuine Toro. If you want a perfect drop-in, buy OEM.

Key Things to Know

• Installation difficulty: Easy – no tools required. Just remove the cover, swap the old foam filter, and snap the cover back on. Takes under 2 minutes.
• Foam vs. paper: This is a washable/reusable foam filter, not a disposable paper one. Rinse with soapy water, dry thoroughly, and re-oil lightly (use foam filter oil, not engine oil) to maintain filtration.
• Common gotcha: Don’t over-oil – excess oil can be sucked into the carburetor and cause starting issues or smoke. A light, even coat is all you need.
• 4-pack value: At ~$3.50 per filter, it’s cheaper than buying single OEM filters. Keep spares on hand or replace more frequently (every 25 hours or once a season).

Should You Buy It

Buy this if you own a Toro mower with a 500/550/575/625 engine series and want an affordable, high-rated 4-pack to keep on hand for quick swaps. It’s ideal for DIY maintenance and offers solid value over OEM singles – just be sure to check your engine model first.
