Oil filters, microns of filtration?

Ok, time to call on the web masters.
I've searched some, was even on Hiflo site, haven't found out How Small they are capable of filtering.

0.001inch = 0.025mm = 25 microns

Oil filter cap has 0.001" - 0.0025" of clearance, currently. We know dirty oil re-mixes with the filtered oil, in a KLR650 and some others.

How small of microns do the "permanent"/re-useable stainless steel or brass KLR oil filters advertise?

I found today, that "MSRHP", "MAXFLOW" and "FLO--->" brands of stainless steel re-usable oil filters claim, "small as 35 Microns".

I also just found that MSRHP paper oil filters are advertising as small as 10 Microns.
That's more like what I'd hoped to find. But alas, they Don't have an application for the KLR650, Bummer!

How about it guys any other brands advertising, 'smaller than 25 Mircons - 0.025mm - 0.001 inch'?

HifloFiltro, paper disposables, on their web site made a Big Deal about TUV (a German testing firm) tested, approved and Monitored.
And Hiflo makes filters for lots of other 'labels'.
But nothing about micron size.

In the Tucker Rocky catalog, it was K&N, not HifloFiltro, which was advertising the TUV endorsement. Go figure!

Paul -

Prompted by your first post, I've searched that topic and come up with nothing.

There was a bit of interesting reading, though, on Harley motors. They spec a 5 micron on the cammer, but a 30 on the Evolution.

And they argue about it! Yay! They're just like us! Except their bikes are loud, go 'potato-potato-potato' and they dress like pirates.

Tom,
From what we just read on that link, it sounds to me like the HDs have the 'test port' on the Wrong side of the oil filter also. ha,ha!
I wonder which side has the pressure gauge or warning light?

Most automotive filters are considered to be 20 micron. That's the number we usually reference. FWIW, 20 micron rating means that the filter is capable of filtering out 50% of the particles of 20 micron diameter. That's harder to work with than knowing that it will remove all of the 20 micron particles but should give an idea. FWIW, if your oil testing is showing good results, moving to a smaller filter media size will result in longer filter bypass time and so longer not filtered oil time. It may have the opposite effect which is intended, particularly in engines which are used for frequent sold starts/short trips. The KLR, IMO, falls into this category most of the time because it has difficulty keeping oil temperatures up.

You're not disrespecting our KLR's by comparing to HD are you? ;-)
