As a follow up, here is the data you were refering to.
Amsoil Oil Filter Comparison
I saw a thread on these forums that also compared to Toyota filters which concluded that Amsoil filters are the holy grail.
But, they, and you, didn't mention that Amsoil's own tests don't show such an improvement over other filters (at 20 microns at least).
I myself use the Ford / Motorcraft FL820S. It's been around for years and is a Purolator Classic / Pure One clone. It got 93.7% efficiency vs 98.7% for Amsoil. Not bad for a $4 conventional media filter.
The two filters that did poorly were the Honda and Toyota. Note it seems that the Honda is a Fram.
It seems the Toyota filter is poor if it comes from Thailand. I heard about this issue also on the Lexus forums and it seems that this is what Amsoil decided to test. Toyota / Lexus quality started to go down from the mid 2000 decade and it seems that this applies to some of the oil filters also. Prior to that, the reviews I saw on Toyota oil filters was very positive and that was what I was relating to.
But in a roundabout way, you have helped to show that Fram is poor compared to the regular suspects (AC Delco is the Chevy filter and Chrysler is Mopar, potentially WIX).
The Honda is a FRAM.
