10 micron.
10 micron
Yes - a 5 micron will filter out much smaller particles than a 30 micron.
a ten micron filter will remove smaller particles from the system, but will also clog faster
5 microns is less than 10 microns so a 5 micron filter removes smaller particles.
7 micron will filter smaller particles than 10 micron.
A 5 Micron is more fine then a 20 Micron, It means, if a particle has a thickness of 1 micron. only 5 numbers of particle can be passed through a 5 Micron filter at a time while 20 numbers of Particle can be passed through a 20 Micron filters. the 5 Micron is more efferent to the 20 Micron.
Micron ratings should be printed on the information panels for each filter. However, different brands may use slightly different processes to test the micron rating, so be sure that different filter brands use the same test before comparing micron ratings between them.
OK If I understand this correctly you are asking if you using a combination of filters can change the properties of a synthetic oil. The answer is NO. Your standard oil filter, filters at a micron rating in the 20 micron range, automotive full-flow oil filter is able to trap and hold essentially all the contaminant particles larger than 25 microns. (A human hair measures approximately 70 microns in diameter. An object that is 1 micron in size is .000039 inches in diameter.) Adding a second filter or Bypass filter to filter out smaller particles is a great way to extend the life of your oil.
50 micron will filter more than 25micron

Common filter sizes in the US are cone shaped filters (#2, #4, and #6) as well as the most popular basket-shaped coffee filter that come in a 8-12 cup size.
cause 0.45 micron is REAL SMALL holes. real good filtration, but easy to clog.
