^ So said the manager, but he also said the AAP TG was made by Fram. And, at the time he was trying to get me to buy something rather than walk out the door empty handed. Didn't pay his comments much heed after the bogus Fram comment. The AAP TG is rated 96/94% efficient.
Now, if the Powerflo is an exact clone of the Puro PP now Classic, it would have a claimed efficiency of 97.5%, which would make it more efficient than the AAP TG (likely more media). That said, the filter study is somewhat older, so the only way to know would be to cut an AA Powerflo open and see. But, if it's close to the Puro PP, the Powerflo price does seem right.
Tough to beat the AAP TG for $1.45 though, and no texture on the Powerflo which I happen to like.
