Would anyone be able to supply a list, and maybe add a column on each row for whether the filter has synthetic media (as that should imply fast flow). Both pieces of information must be included when stating the micron rating of a filter Removes particles as small as 25 microns high capacity for trapping and holding containments 0.5mm thick steel cans withstand high pressure operating conditions rough surface for enhance grip provided by

A filter that is 95% efficient at 20 microns can capture 95% of particles that are 20 microns or larger
The same filter may only be 50% efficient at 10 microns, meaning it captures half of the particles that size or larger.
Here's a comparison of the results to the advertised filtration rating of the filter from their manufacturer Here's the graphs for the data The next two are close ups of the most efficient filters The last one is the flow data.
Digging deeper, i found that the filter manufacturer reported 95% efficiency at twenty microns but a little more than 50% efficiency at ten microns Nominally rated filters should never be used for critical applications. The “20” media is much more effective than the “50.” figuratively think of the 20 as a paper coffee filter and the 50 as a pasta strainer, a greatly exaggerated example The larger the first number the better, and the smaller the second number the better.
Amsoil ea oil filters have one of the best efficiency ratings in the automotive market providing a filtering efficiency of 98.7 percent at 20 microns
Copied and pasted from amsoil website Hello everyone, this is a cut open oe plus pro series oil filter prs9715 which fits many subaru models, including my subaru legacy gt with the fa24 engine It was bought from a canadian tire in canada On the box it lists which filters it directly replaces including the wix 57055
A chart below gives micron filter capacity and efficiency for some filters, but the list is incomplete It also lacks data for two brands that it included on its list In a such case, the filter can be said to be 20% efficient at 5 microns or have a micron rating of 5 at 20% efficiency
