This was a email that I received from K&N about the HP-6001 oil filter. The last comment kinda scares me, what do you think?
They claim 10 to 20 micron, so I was asking at percentage.
""Dear Christopher
Single Pass 90.92% Avg. Efficiency 89.51%
The media is composed of 94% cellulose, 3% polyester fiber, and 3% micro fiber. The wood based cellulosic fibers provide the basic maze of inter-woven "filtering" structure and provides depth and bulk to the sheet. The synthetic polyester fibers reinforce the cellulosic fibers to help the paper withstand high temperature and increase the tear or fatigue resistance. The micro glass fibers are extremely small in diameter and are used to create a very fine pore structure, while allowing minimum restriction to filtered flow. The combination of these components provide premium filtering efficiency, capacity, and life. We consider the glass to be a positive rather than a negative feature.
