Briggs & Stratton engines use one of three types of air filters: paper, foam, or dual element. [0]

A paper air filter element works by causing any air that is intended to enter the combustion chamber of the engine to pass through a filtering device made with microscopic holes in it. [1]

The paper element traps the dirt particles on the outside of the element. [9]

A particulate air filter is a device composed of fibrous or porous materials which removes particulates such as smoke, dust, pollen, mold, viruses, and bacteria from the air. [10]

Combination air filters provide the highest degree of air filtering in the industry. [4]

If the air filter element is foam only, it MUST be oiled and serviced regularly. [2]

Your foam filter requires replacement every 3 months or after 25 hours of use, whichever occurs first, more often under dusty conditions. [3]

Your Paper Air Filter should be replaced every 3 months or after 25 hours of use. [7]

Carefully remove and discard paper cartridge. [8]

Before installing new filter, follow the oil change procedure in the operator's manual. [5]

Lightly oil gasket with fresh clean engine oil. [6]
