Most of the time, I see filters stating their efficiency based on the ISO 4548-12 testing method with a micron size of 20.
I'm looking at a Mahle filter which states, "...The filter can even remove up to 95 % of tiny particles just 10 ìm in size"... Source: https://bit.ly/3fWduIO
So I can compare the Mahle cartridge to other brands, is there a way to extrapolate what the filter efficiency is at 20 micron particle size (i.e., like most of the other brands)? Is there a way to calculate this? I'm sorry if this is an obvious and easy "conversion".
Thank you!
