Briggs offers 4 filters that will fit your engine. Some have more filtering media. Post the engine numbers that are stamped on top of the valve cover and someone will respond with the exact Briggs part number specified for your engine. The Briggs numbers will cross over to filters offered by most of the auto stores. The last time I checked, Napa offered 3 different filters that are listed for a V twin Briggs.

Many of these are manufactured by the same manufacturer.
