If the pump is force fed by another pump sometimes called a supercharge pump use of a low micron rated element is possible. Some vehicles are said to have extended the drain intervals for up to 5 10 times.

Lowest micron oil filter. As you mentioned they use a stainless steel mesh that these companies rate in the neighborhood of 30 microns of filtering capacity. This oil filter type is a type of a bypass filter that allows longer oil drain intervals. Like the micron ratings lower than this 10 micron rated filters tend to clog quickly. 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. A micron level is what size of contaminant the filter in question can remove. 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. Ive looked into the specs of a couple of these filters. 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. It will be able to filter out that bacteria as well as anything larger than 1. Misunderstanding efficiency and micron rating can result in selecting a filter that is not appropriate for the application under consideration. Passenger car and light duty truck oil filters typically have an absolute micron rating in the range of 25 30 microns.
Typical filter locations with micron ranges and bypass settings. Some manufacturers offer inlet filters with ratings as low as 25 microns. 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. With the high efficiency oil filters pore sizes that are 3 micrometers engine wear from continuous contaminant filtering is reduced. These low micron elements have large filtering surfaces.
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. In laymans terms 1 micron is equal to one millionth of a meter or 000039 inch. 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.
