Frequently Asked Questions

Do I need to oil this foam filter before installing it?

Yes. Foam air filters usually need to be lightly oiled to function correctly. The oil acts as a magnet, catching and holding the microscopic dust particles as the air passes through the foam.

How do I oil the foam filter properly?

Pour a small amount of clean engine oil onto the foam filter. Squeeze the foam repeatedly to distribute the oil evenly throughout the material, then firmly squeeze out any excess oil so the filter is damp but not dripping.

Can I wash and reuse this foam filter?

Yes, genuine Briggs & Stratton foam filters can be washed. Use warm water and liquid dish soap to clean out the dirt and old oil. Squeeze it dry, allow it to air-dry completely, and re-oil it before reinstalling.

How often should I clean or replace my lawn mower air filter?

You should check and clean the foam filter every 25 hours of operation or at least once a season. It should be completely replaced every 50 hours, or immediately if the foam begins to crumble or tear.

What happens if I run my mower with a clogged air filter?

A clogged filter chokes the engine of air, causing it to run 'rich' (too much fuel, not enough air). This leads to poor fuel economy, loss of power, black exhaust smoke, and fouled spark plugs.

Will this fit my Briggs & Stratton 450E series engine?

Yes, the 799579 filter is the exact genuine replacement part for the 450E series engines, as well as the 300E, 500E, and 550E series.

Is this an original Briggs & Stratton part?

Yes, this is a 100% genuine OEM Briggs & Stratton replacement part, ensuring proper fitment and maximum engine protection.

Why is an exact fit so important for an air filter?

If an aftermarket filter is slightly too small, unfiltered, dirty air will bypass the filter entirely and get sucked straight into the engine, which can rapidly destroy the internal piston rings and cylinder walls.

What are the exact dimensions of this filter?

The filter measures 4 1/4 inches (108mm) in length, 3 1/4 inches (83mm) in width, and 7/8 inch (22mm) in height/thickness.

Can I use water to clean the foam filter?

Yes, warm soapy water is the best way to clean a foam filter. However, you must NEVER reinstall the filter while it is wet. It must be completely dry and freshly oiled before going back into the mower.

Will this filter fit my ride-on mower?

This specific filter is generally used on push mowers (walk-behind mowers) featuring the smaller 300E to 550E series engines. Ride-on mowers typically use larger, pleated paper cartridge filters.
