I'm looking for a filter that filters 3 microns or smaller, its going to be for my truck and from what I've read people said to run a 3 micron oil filter funny thing is they never mentioned a brand.

As of now I'm thinking:

Purolator---Pureone---99.9%---???
Napa---
AMSOIL Ea
Fleetguard

What I think might be nice is to try to make a sticky with:

Filter Brand---Filter---Efficiency%---Micron Filtered

Purolator---Pureone---99.9---???
Purolator---Purolator---97.5%---???
Purolator---Synthetic---99%---???
AMSOIL---Ea---98.7%
AFE---PROgurad---95%+ (hard to tell from the graph)
Napa---Gold---???---???
Napa---Platinmun---???---???

Its a start I'll keep digging

Just returned from Walmart, the Fram Ultra is stocked now. Definately include that in the list.

Fram Ultra is 99% ISO 4548-12 for particles >20 microns

Most of the ratings you mentioned are at 20 microns. Few filters will do much at 3 microns, and if they did you'd have flow issues.

I believe the PureOne is closest to what you're looking for though.

Three microns as a primary oil filter? You won't find it and if you did it would have to be huge to be able to flow the volume of oil needed.

Are you sure they weren't talking about fuel filters? There has been a big hoopla lately over Cummins fuel filters because some of the aftermarket ones you buy are only 10-12 micron and it's allowing too much dirt into the system and eating injectors. And engines too, if it's allowed to go too far.

Anyway, the only 3 micron oil filter you would want is a bypass system.

There's no way to filter down to 3 microns at the flow rate an oil filter sees. That's about the size a backpacking water filter gets down to, and if you've used [a decent] one once you know what the flow rate is, maybe a gallon a minute at high pressure.

Do you mean for a bypass or ???

I think your right it was a fuel filter, well at least that mystery is solved now I got to find a dumb fuel filter...

I would go for a WIX or Donaldson or Cummins. I assume you want a fuel filter for your Cummins? Check Genos Garage online. They sell genuine Cummins parts before Chrysler has put a Chrysler label on them and doubled the price.

Fleetguard are quality filters also. What are you digging for?

Some dinero to fund the purchase?

Fleet guard does 7 microns, AFE 5, and Purolator does 3-4 I emailed them. Oh and by digging I meant research.

I've seen a few studies in which folks tried to determine "pore size" and such by using analytical equipment, and the ASTM/ISO tests are more about filtering out standardized dust samples than smallest pore sizes, but the smallest number I recall reading was 8 microns for a PureOne media. (And yet, PureOne medias were nothing special in other shadetree scientist tests.) Bottom line, I've seen very few references to sigle-digit micron ratings for full-flow (standard) oil filters, as well as air filters. In one piece of Hengst oil filter literature they refer to "reliably filtering out" 10 micron particles, which was good enough for me since I liked the Hengst construction anyway. But searching for 3 micron filtration outside of bypass filters is a snipe hunt, comparable to Snooki searching for her brain. Limted chances for success. :-)

Baldwin is also a good filter(fuel, air and lube)

contaminating particulates that are 3-7 microns in size will not damage engines significantly; oil flow is an issue.
