I talked to an AFE rep. They have a synthetic fiber dry filtering material, not paper. He was not able to answer my question of % filtering efficiency with the standard SAE test. He did say they stop all particles larger than 1.5 microns.
They will be available later in the year (summer/fall) for about $70.
