Thought I recognized the testing procedure. " I have to give credit where credit is due, so thanks to Robert J Tracy (river_rat on BITOG)" . The OP duplicated r_r's testing procedure done/posted on Bitog, this time using some different filters. That said, the OP here confused most of the adbv material id's, the orange/red and purple and blue are all silicone and the black are nitrile.
I'll have to look at the rest of results closer but some look to mirror r_r's results. The OEM no endcap type again showed as relatively inefficient.
Beyond the testing, some good basic filter reference material in the thread.
