Don't think I've seen that specifically noted before. The one I referenced from the rep saying, "99.9% efficient > 30um and 97.22% efficient > 20um" as posted
HERE .Guess there must be some confusion on the rep's part about the spec on the Ecogard Synthetic box. I didn't see a discrepancy noted in the link.
So it would seem Ecogard similar to STP XL in COO and efficiency.
Yeah, I missed it on the box the first time till it was pointed out to me.
As for the numbers, that is what he told me (the 99.9% @ 30), which could technically be correct, and the 25 micron rating could also be 99.9%, then the 20 micron is the 97.2%.
Still decent numbers IMO.

But when you start claiming ISO ratings, you better be able to back it up. Apparently EcoGard is a large player in supplying quick lube shops and such. There is no benefit long term to make false claims. At least they are giving numbers, unlike many OEM makers and other made in China filters.
