HIPA (Pack of 2) 792105 276890 Air Filter Cartridge Compatible with BS 593435 593240 407777 40G777 40H777 445667 445877 44H777 Engine Lawn Mower Z425 GY21057 MIU11515 MIU11517

What It Is

This is a pack of two replacement air filter cartridges (model 792105 / 276890) designed for select Briggs & Stratton single-cylinder engines used in riding lawn mowers, zero-turn mowers, and some commercial turf equipment. It traps dirt and debris before they enter the carburetor, protecting engine performance and longevity.

Fitment & Compatibility

Before buying, verify your engine’s model number (stamped on the valve cover or blower housing). This filter fits Briggs & Stratton engines with numbers like 593435, 593240, 407777, 40G777, 40H777, 445667, 445877, and 44H777. It also replaces OEM part numbers 792105, 276890, and crossover numbers (e.g., John Deere GY21057, Husqvarna MIU11515/MIU11517). Common mower brands include John Deere Z425, Husqvarna Z242F, Toro TimeCutter, and Craftsman Z540. Measure the filter cavity – these are roughly 3.5” wide x 2.5” tall – and confirm your current filter matches the shape (rectangular with a foam pre-filter on one side). If your engine uses a different mounting tab or a round filter, this won’t fit.

Key Things to Know

• Quality: HIPA filters use pleated paper media and a foam pre-filter comparable to OEM, but the foam may be slightly less dense. Fine for residential use; commercial operators may prefer OEM.
• Installation: Tool-free – remove the old filter, slide in the new one, and close the cover. Ensure the foam side faces the engine intake (not the cover).
• Gotcha: Some mowers have a separate foam pre-filter that slides over the paper cartridge. This pack includes the foam attached. If your housing expects a loose foam wrap, you may need to trim or adjust.
• Frequency: Replace every 100 hours or annually, more often in dusty conditions. A dirty filter causes hard starting and power loss.

Should You Buy It

If you have a compatible Briggs & Stratton engine and need a budget-friendly, reliable filter for residential mowing, this two-pack is an excellent value. For heavy commercial use or if you demand exact OEM foam density, stick with Briggs & Stratton’s genuine part.
