It was found that most 2 micron filters on the old standard were 5-7 on the new standard, so some filters are even better but rated higher.

So what I gathered was that Baldwin and Fleetguard now report on the new standard... which is a change and why many refer to the filters as 2 microns... And Cat and Donaldson still report on the old system.

So the Baldwin BF7633 meets all the requirements of the 1R0750, and I can get the 7633 for about $4 cheaper, so thats what I will run...

It kinda annoyed me that companies are reporting ratings based on 2 standards... but they all filter about the same...

Interesting.....good stuff man!:thumbsup
