HOODELL 491588s Air Filter with Pre Filter, Compatible with 491588, Toro 20332, Craftsman 3364, Premium Lawn Mower Air Cleaner

What It Is

The HOODELL 491588s is a replacement air filter kit (main filter + pre-filter foam) for small engines used in walk-behind mowers, zero-turn mowers, and some lawn tractors. It’s designed to trap dirt and debris before they enter the carburetor, helping maintain engine performance and lifespan.

Fitment & Compatibility

• Check your OEM part number: This replaces 491588, 491588s, and OEM numbers from Toro (20332) and Craftsman (3364).
• Measure your filter: The main filter is roughly 4.5” x 3” x 1.5” (L x W x H). Verify dimensions against your current filter.
• Engine brands: Fits Briggs & Stratton, Kohler, and Toro engines that use a rectangular paper filter with a separate foam pre-filter. Common on Toro TimeCutter, Craftsman T110/T120, and similar.
• Not universal: Won’t fit round or cylindrical filter housings. If your mower uses a single foam-only filter, this won’t work.
• Pre-filter note: The included foam pre-filter wraps around the paper element. Ensure your air box has space for both layers.

Key Things to Know

• Quality vs OEM: Foam pre-filter is slightly denser than genuine Toro/Craftsman, but paper element filtration is comparable. Works fine for residential use.
• Installation is easy: Remove old filter, clean the air box, slide in new filter, and secure the cover. No tools required.
• Common gotcha: The pre-filter must be lightly oiled (foam filter oil) for best dust capture. Running it dry reduces effectiveness.
• Longevity: Replace every 25–50 hours of mowing, or once per season. Change sooner in dusty conditions.

Should You Buy It

Yes, if you own a compatible Toro or Craftsman mower and want a budget-friendly replacement that performs as well as OEM for residential mowing. Skip it if you need a filter for commercial use or a non-rectangular housing.
