The real world is the real world of cars driving on roads, not a machine on a bench in a room loaded rapidly with particles because they have no practical way to duplicate any better the real world.
Thats why we see someone running 400k on a supposedly less efficient Toyota filter. But in reality it is likely very efficient compared to others like it or the engine would be worn out from all those “particles.”
Members here have done particle counts using the Fram Ultra and I see the the results as pretty much the same as others, sometimes worse than others. Nothing to get excited about.
