The Extra Guards use a silicone ADBV now too.1. No oil filter can remove everything
2. Oil filters become saturated with particulate matter over the duration of their usage. In my experience with a Hyundai GDI engine, that has a reputation for producing an excessive amount of carbon soot, it can effectively cut the expected usage in half or more.
I could not tell you, perhaps the Honda filter is more like a Tough Guard? It does use a silicone ADBV.
