Pablo is right.
AMSOIL licenses the SYNTEQ media from Donaldson for their EaO filters. It is the best filter media in the world. If AMSOIL's numbers are the same as the Donaldson SYNTEQ filters in terms of efficiency, then the only thing comparable is going to be a Fleetguard with their synthetic glass media, which seems to be basically identical (this omits the dual-stage Stratopore filters with built-in bypass filtration).
You look at what works in the Diesel world. They have 10-micron ratings for all their filters at 2 flow ratings. In my research for "the best oil filter", I looked at all the readily available filters and Donaldson was the most efficient.
This is much easier with Diesel filters because of the standardized testing method spec'd by Cummins. We do not have that data for automotive filters.
