You missed the whole point. Go read it again.
Then what ... believe that the Boss is "99% @ 25u" like Purolator says on their website?
Their Spec Sheets only proves that their website is misleading, at least on the Boss. I better check the other two models.
I specifically asked Fram what the efficiency was on a couple of their efficiency claim model filters (see post 79), and they said they were 99% @>20u. So since you believe that lack of sufficient data isn't a conspiracy, then I guess Fram was accurate and truthful in their answer to my question without including a Spec Sheet.
