Both filters will essentially remove their respective percentages of particles 20 microns or larger in diameter including virtually all particles large enough to be visible to. For example if bacteria in your water are 1 micron and you have a filtration system with a micron level of 1.

Lowest micron oil filter. Passenger car and light duty truck oil filters typically have an absolute micron rating in the range of 25 30 microns. Lets start with what is a micron. Depending on what region you live in your vehicle can be tested by some pretty extreme road conditions and harsh weather. Some vehicles are said to have extended the drain intervals for up to 5 10 times. Like the micron ratings lower than this 10 micron rated filters tend to clog quickly. With computer systems running a lot of the engine functions in new cars these days vehicles have some of the most efficient systems ever.
Micron levels in water filtration are usually between 5 and 5 microns. In laymans terms 1 micron is equal to one millionth of a meter or 000039 inch. This oil filter type is a type of a bypass filter that allows longer oil drain intervals. Ive looked into the specs of a couple of these filters. Misunderstanding efficiency and micron rating can result in selecting a filter that is not appropriate for the application under consideration. If the pump is force fed by another pump sometimes called a supercharge pump use of a low micron rated element is possible.
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. These low micron elements have large filtering surfaces. With the high efficiency oil filters pore sizes that are 3 micrometers engine wear from continuous contaminant filtering is reduced. It will be able to filter out that bacteria as well as anything larger than 1. Filters with a 10 micron rating can remove some unseen materials from liquid but not bacteria or viruses. Purolator classic oil filters are 975 percent efficient and purolator pureone filters are 999 percent efficient the highest efficiency ratings on the market.
Typical filter locations with micron ranges and bypass settings. A micron level is what size of contaminant the filter in question can remove. Top oil filters in its lineup include the mobil 1 m1 102a extended performance oil filter and mobil 1 m1 113 extended performance oil filter. Some manufacturers offer inlet filters with ratings as low as 25 microns. As you mentioned they use a stainless steel mesh that these companies rate in the neighborhood of 30 microns of filtering capacity.
