For all three brands he mentioned? Sheesh. He must be real G'd up to get 3 companies to write him checks.
Anyway, Donaldson makes the DBL7349, which is 100% @ 20 microns.

You think? I'm not so sure, that troll had an inordinate obsession with Mobil 1 that I haven't see with this one yet. What makes you so sure?
This one seems more stuck on filters than oil, IMO.

Thank you
Well, the Fleetguard Stratapore Venturi that I use on my Ram has a rating of 60% at 10 microns-

Not sure if any are made for your (unknown) application, though. Starting to understand why the knowledgeable long-time BITOG people are starting to give up, too many people that are too lazy to search for anything, & bash the members that DO respond!

Yep, I vote for BigDaddy / Mrsandmand reincarnation. Troll stink is easy to detect.

Amsoil EA is posted as 98.7% @20 microns so I'm guessing the 5 micron number is lower but probably still pretty good.
The Ultra gets the better rating because it uses two layers of media instead of 1 thicker layer like the Amsoil and royal purple does. They also seal it very well with deep end caps with lots of adhesive and even use an extra seal on the bypass valve, sometimes leakage in these areas effect the ISO 4548-12 ratings.
Donaldson makes some very high efficiency synthetic filters too if you can cross them to certain larger automotive filters.
+1 ... any of those will satisfy the OP's requirements IMO.

Mann is 99.9% at 9um.
Appreciate all the constructive comments and suggestions.
I went out and bought a Purolator Boss (PBL30001, Fram size is a XG8A). Seems like the Boss was designed to last a long time, but may not filter quite as well (sub-20 micron) as the Fram Ultra.

Will you leave it on for the whole 15k?
I like what I've seen of them. You probably seen some cut and post of new unused ones here?

Not here it's not, because our Manns (unless it's a German car) are rebranded Purolator classics. They only stop 99.9% of the particle size that's infinitesimally larger than the biggest media tear.

Rebranded filters that started out as junk are still junk, no doubt, but proper Mann are not junk, they're among the best available.

if efficiency is of such importance: municipality with idling truck etc etc etc go grab a microgreen!
watch?v=HDFWjQvLpM4 this guy on YouTube used a microgreen as you can see he should have changed it quicker! but men this filter is insane. the amount of particle it trap at the bottom is awsome(he nickname his truck ( a 1996 tahoe)SLUDGE MONSTER.rofl
watch?v=dOnerEiP1ks here a video about the mechanic of the filter it self ,nvm the publicity lol!

That's true, but getting a real Mann for a North American or Japanese application is an exercise in futility. The same goes for Bosch (which are basically Purolator P1s). Heck, at one point at least, even the Bosch site would point to Purolator Classic or P1 numbers for a fair number of Japanese and North American applications, with a clone not even being available.

Can you provide a published link/citing to that spec? As it 'seems' quite an impressive spec, like to see the ISO test procedure attached to it.

'If true', one only has look as far the front door of Mann&Hummel corporate to find the culprit. After 10 years of partial and full ownership of the NA operations, no excuse for the poor or nonexistent leadership. Can't pass the buck at this point.

i bought a couple of these and slaped one on as a spin on atf filter. I had a glass media filter on there for quite a long time until now and it clearly coulda stayed in for so much longer. I suppose i might only change the microgreen after about 60k. I wouldnt advise that on an engine block but the tranny isnt accumulating or making very much crud at all compared to an engine.

Mann's are very good filters and they are my first choice for euro vehicles but i dont really think they come close to 99.9% at 9 microns.
In fact, i think most premium oil synthetic media oil filters have a much better efficiency spec than a Mann.
