You cannot guess the efficiency of a liquid filter. Commonly used fuel filters may have multiple efficiency ratings describing their performance.

Micron ratings for fuel filters. This filter needs to protect the pump from damage. High performance fuel injector manufacturers recommend a 10 micron or finer filter. Fluid filters can have a micron rating which expresses the filters ability to remove contaminants based on the size of the particles. However 10 micron is still very small and can benefit many industries from oil to chemical plants because of their ability to filter so much. 1 to 40 micron. For example a filter may be described as being 50 efficient on 2 micron particles 75 efficient on 12 micron particles and 98 on 23 micron particles.
This rating filters a little less than the 5 micron rating. Filters with a 10 micron rating can remove some unseen materials from liquid but not bacteria or viruses. You cannot guess the efficiency of a liquid filter. For example a filter may be described as being 50 efficient on 2 micron particles 75 efficient on 12 micron particles and 98 on 23 micron particles. This filter is often difficult to change without introducing air into the system. 25 to 400 micron.
Like the micron ratings lower than this 10 micron rated filters tend to clog quickly. Fuel system final filter after the pump. For example a filter rated for twenty 20 microns means that the filter will capture and contain all particles in the fluid that are 20 microns and larger in diameter. Fuel system pre filter before the pump. Its usually expensive and sometimes difficult to access. 1 micron 001 mm.
A micron rating for a fuel filter is a generalized way of quantifying the ability of the filters media to remove contaminants of a particular size. Many folks prefer to use a 2 micron filter because they dont want to deal with the on engine primary filter and i cant say i blame them. For example a filter with a micron rating of 7 will filter out contaminants of 7 microns or larger and a filter with a micron rating of 3 will filter out contaminates of 3 microns or larger. Commonly used fuel filters may have multiple efficiency ratings describing their performance.
