Cofee filter is a 40 microns, not good enough and cloggs quickly and is really slow. I'd say, don't even try, I did that for you. Not worth! That's why I keep decanting. It's free and i have time to run those 5k miles anyway ...
How do you know coffee filters do 40 microns, is there a listed spec for that somewhere?
Here's another idea: The Fram Ultra glass-fiber oil filter gets out 80% of all particles at 5 microns and larger, and of course its as you drive. Also, the Micro Green oil filter gets out particles from 3 microns and bigger, again as you drive, built into the oil filter media. Another note: In another bitog discussion, we found out that carbon soot particles from direct-injection DI engines are in the 0.001 to 0.3 micron range, so they float and won't filter out either.
Yea, a long time ago I googled and found that the absolute for cofee filter is 40 microns. The soot below 1 micron doesn't bother me much, but the metals and dust powder above 3 microns does. I can't buy those filter with fine synthetic media in here, they're imported and endup costing a lot after shipping and tax ... I'm stuck with decantation, man!
