Yeah, the link only says 99.9% efficiency, no stated micron size in relation to that.

Royal Purple states 99 at 25 microns. Probably still >97% at 20 micron. FWIW, I like the M1 EP and Amsoil EaO filters a lot as well.

RP states results for 25, 20 and 10 microns:

@ 25 microns - 99%
@ 20 microns - 98.7%
@ 10 microns - 80%

I'd like to see more filter results @ 10 and 15 microns.

I would like to know what the OP is talking about as well? The RP filters are one of the best out there and their performance backs up any claims made about them. Not sure what propoganda is being referred to?

I have been using them because I wanted a filter with fully synthetic media, and RP filters were the easiest for me to find.
