I cannot confirm my statements anymore than yours.. I just post what the specs are on the filters that I currently have installed in my truck and the one fuel filter I have installed on my tractor. The 100 Microns specification came from one of the Mr Filter pages.. Also notice while the specs for my filters are readily posted at the manufacture web sites, MR Filters are not. or are not long longer. The excerpt I provided above was from one of their early advertisements in one of the tractor rags I searched all over their website for the info..
Also for your edification
Water will pass through 100, 50 and 1 microns just fine.. The reason it doesn't pass through in our filters is its need and want to stick to itself due to cohesion surface tension, call it what you want. The teflon coating causes it to repel. It is hydrophobic.. This is why the instructions say dont let too much get in there because "head" pressure will allow it to pass at some point.
Back to the point.. To ensure safe drinking water you want an emergency water straw with .1 microns.. The little (point) is important because it is neither 5, 7, 50, nor 100 microns.. It is one tenth of a micron.. This is how you allow water molecules to pass and keep larger molecules such as bacteria, diesel (yes), and other solids out.
The reason your filter works at least in my mind is diesel doesn't have the same surface tension and cohesion factors that water does.. It is not repelled by the Teflon and has an innate want to exercise adhesion to things so it willingly splits and goes through the 50 (100 whatever) micron filter. And water molecules although much smaller than diesel are molecularly heavier than diesel and really are attracted to each other.. I don't care what micron any of us are using all but the tiniest easy to clog filter will let it through. matter of fact under pressure the tinier filters will let water through and not the diesel.
If you do your research, research diesel marine engines.. Where it is recommended to have a 2 micron filter and a pressure gauge installed so you know when it clogged and you went into bypass.. Or even more clear they 10 micron filter from the tank on the low pressure side and 2 micron filter on the high pressure side not all of them but that it industry standard and recommended.
