Thanks!! Box needs updating too.I called Highline Warren again today, and the filter Tech Line guy put me on hold and went digging around and came back and said he did have some documentation that said the Mobil 1 Extended filter was 99% @ 20u. I asked if there was any reference to ISO 4845-12 in the info he had, and he said he didn't see anything like that.
So it sounds like this new Mobil 1 is essentially like many of the PGI made filters coming out of Asia, and maybe this Mobil 1 filter is essentially using the same basic media. That's all I could find out. I told the guy if these are 99% @ 20u, then Mobil should put that info on their website since it would attract more buyers than if no specific efficiency info was given.
