593260 Air Filter for Lawn Mower, 798452 334404 Replacement Air Filter Compatible with Toro Series Engine 550E 500EX 550EX 625 575EX 4247 5432 5432k, 2 Packs

What It Is

This is a replacement air filter (2-pack) designed for Toro engines in the 500E, 500EX, 550EX, 550E, 575EX, and 625 series. It fits lawn mowers with model numbers 4247, 5432, and 5432k. The filter traps dirt and debris before it enters the carburetor, protecting engine performance and longevity.

Fitment & Compatibility

Before buying, verify your engine series – this filter fits Toro engines labeled 550E, 500EX, 550EX, 625, 575EX, and 625 series only. It also matches mower model numbers 4247, 5432, and 5432k. Cross-reference with OEM part numbers 593260, 798452, or 334404. This is an aftermarket replacement, not OEM Toro. Physically measure your old filter (roughly 4.5” x 3.5” x 1.5”) to confirm dimensions. Not compatible with Briggs & Stratton, Honda, or Kawasaki engines.

Key Things to Know

• Quality tip: The foam pre-filter on this aftermarket version is slightly denser than OEM, which may require more frequent cleaning in dusty conditions.
• Installation: Tool-free – just remove the air filter cover, swap the old filter, and re-secure the cover. Takes under 2 minutes.
• Common gotcha: Some users report the foam layer can separate from the paper element if you wash it aggressively. Hand wash gently with mild soap and air dry.
• Maintenance: Replace every 25 hours of use or annually, whichever comes first. Clean the foam pre-filter every 5 hours in heavy debris.

Should You Buy It

If you own a Toro mower with one of the listed engine series (500E, 550EX, etc.) and want a reliable, budget-friendly replacement that matches OEM fitment, this is a solid choice. It’s ideal for homeowners doing routine maintenance – just confirm your model number or measure your old filter first. Avoid if you require an exact OEM part for warranty purposes.
