I'm sure this must have been posted before, but still a good look at filter operation and some points on poor quality filter designs.

^I believe it's the other way around.
The OE 'fleece' Mann+Hummel cartridge filters in our Mercedes-Benz proved to be excellent performers.
Thanks for the video...I'm a visual learner.

Great video. Thanks for sharing.

So, you're saying we KNOW they aren't ignorant?

Stating the obvious (for some at least), lots of irony in this yt considering that Mann has been half owner since 06 and sole owner since last year, of Purolator.

AAP carries them.

^Yes, I used a MANN version of a 14459 for my car a couple years ago from AAP and instantly thought it was a Purolator Classic. Looked up, and it seemed plausible. I forget if I truly confirmed that with what I found or not, I'm sure it was on this site. lol.
What's the efficiency ratings on this filter?
@daman not sure but I don't have time to look it up atm. Here is the cross-over Mann p/n:
http://www.amazon.com/Mann-Filter-ML-1002-Oil-Filter/dp/B001DRJNHA
a 1002, so compare that to the L11459? Which I also don't know the rating of that specific one.

That's fine thanks I guess that question was directed at anyone.

Thanks! I actually finally have an AAP going up near me and will open soon. Before this I only had NAPA, O'Rielly, Pep Boys and Autozone.

I did a brief search and didn't find much in the way of efficiency ratings for MANN filters. I'd wager it's about the same as a Purolator Classic, though. Just from seeing the type of element from cut open/side-by-side pictures.
Granted, that doesn't guarantee media properties, but more of a gut conclusion given the limited information they give about their filters. At least, in the NA region. Maybe in Germany they have all kinds of info.
Here are some older BITOG threads. A couple show they probably have ratings at larger micron. Though one claims 9 micron
?!

That was from a 'forwarded' US sales person email with a returned German answer wrt efficiency of a particular MANN filter p/n.
Just go to AAP, search mann, ignore vehicle spec and look at them filter at a time. The spin-ons don't seem to have efficiency spec but the cartridges are listed generally around 99% @ 40micron.
Case in point, this cartridge has a 99% efficiency at? 38.7 micron. .7 of a micron to get that efficiency of 99% as desired I guess.
http://shop.advanceautoparts.com/p/mann-...mann#fragment-2
Others varry, result 2 has a cartridge of 99% but at 38 micron. I think they just show w/e micron they achieve 99% efficiency at at least wrt their cartridge.
Perfectly in line with a Puro rated at 97.5% at 25micron, eh?
