HOODELL 3 Pack 491588S Air Filter with Pre Filter, Compatible with 491588 493537 493537S Toro 20332 Craftsman 33644, Push Lawn Mower Air Cleaner

What It Is

This is a 3-pack of replacement air filters (part 491588S) with pre-filters for push lawn mowers, designed to trap dirt and debris before they enter the engine. It’s a direct fit for many Toro, Craftsman, and other small-engine mowers using the 491588, 493537, or 493537S filter.

Fitment & Compatibility

• Check your current filter part number – Look for 491588, 493537, or 493537S on the old filter or in your owner’s manual. The HOODELL pack is an aftermarket equivalent, not OEM.
• Measure the filter – This pack fits filters roughly 3.5” x 2.5” x 1.5” (including the pre-filter). Confirm your mower’s air box dimensions if unsure.
• Common compatible models – Toro 20332, Craftsman 33644, and many other push mowers with Briggs & Stratton or similar engines that use this filter shape. Not for zero-turn, riding mowers, or large commercial decks.
• Deck size is irrelevant – The air filter fitment depends on the engine model, not the cutting deck. Verify your engine brand and model number.

Key Things to Know

• Quality is good for the price – Users report a snug fit and no performance issues. The pre-filter adds extra dust protection, especially in dry or dusty conditions.
• Installation is simple – Remove the old filter, wipe out the air box, slide in the new one (pre-filter facing out), and secure the cover. No tools needed.
• Pre-filter is washable – You can rinse and dry it a few times before replacing, extending the life of the main filter. Don’t oil it.
• Not OEM, but reliable – This is a generic aftermarket part. It won’t have the exact same foam density as a Toro/Craftsman branded filter, but it works fine for most residential use.

Should You Buy It

If you have a push mower that uses the 491588/493537 filter and want a budget-friendly 3-pack for routine maintenance, yes. It’s a solid value for the price, easy to install, and the pre-filter is a nice bonus. For commercial or heavy-duty use, stick with OEM.
