From http://www.amsoil.com/storefront/eao.aspx "Absolute Efficiency
AMSOIL Ea Oil Filters (EaO) have the best efficiency rating in the automotive/light-truck market. EaO Filters provide a filtering efficiency in accordance with industry standard ISO 4548-12 of 98.7 percent at 15 microns, while competitive filters containing conventional cellulose media range from 40 to 80 percent efficiency.

Less Restriction
AMSOIL Ea Oil Filters have significantly lower restriction than conventional cellulose media filters. Their small synthetic nanofibers trap smaller particles and hold more contaminants, resulting in lower restriction. During cold temperature warm-up periods, an EaO lube filter allows the oil to easily flow through the filter compared to a typical cellulose filter. Lower restriction decreases engine wear.

More Capacity
A filter’s capacity refers to the amount of contaminants it can hold and still remain effective. AMSOIL EaO Filters have a greater capacity for small, wear-causing contaminants than competing filter lines do. In most applications, when used in conjunction with AMSOIL synthetic motor oils in normal service, EaO Filters are guaranteed to remain effective for up to 25,000 miles or one year, whichever comes first."

Of course one of the ways to get even smaller particles filtered out is to use the AMSOIL EaA 100,000 mile air filter which absolute efficiency is 2 microns to keep out larger dirt/dust particles out of the oil in the first place.
