Your theory is all wrong. The large particles just sit on the surface of the nanofiber web. Since the nanofiber web has several times the number of pores and surface area compared to a microfiber web, it can trap more particles yet provide more flow. Donaldson has done extended oil filter intervals for 20 years with this design and AMSOIL has marketed extended 25,000 mile oil filter extended change intervals for 5 years for autos, light trucks and up to 15,000 miles in motorcycles. And SouthWest Research Institute in San Antonio has extensively tested these filters. They work as advertised. Thousands of used oil analysis also confirm.
