Why do you think your PCs didn't follow the same trend? Still a possibility something was not right with the filters or the PC test itself. Why did both of Patrick's repeat and come out like expected knowing the efficiency rating? Both Microgreens repeated, and weren't even on the same vehicle (probably not the same filter model either). Why does the less efficient Boss show a worse ISO Code as expected? Go gleen PC data in the UOA forum and look at the trends. There might be some outliers, but the ISO efficiency to ISO PC correlation is obviously there in most cases.

You know I collected the sample with a sample pump, and you know the filter wasn't loaded up because it is here cut open and there is no evidence is was bypassing or defective in any way. Additionally there are 2 particle counts on the same filter with essentially the same result.
