For whatever it's worth:
Thanks for contacting K&N. The K&N HP-2010 is a 5 micron oil filter but it is most efficient between 10-20 micron range where its tested to achieve 99% efficiency. I do not have the beta ratio available from a multi-pass test but I'll email our engineering department to see if that's available.
Thank you,
