I don't doubt it. I wonder what the Bosch "Distance Plus" is going to be then? Maybe deeper pleats for longer OCIs? I can't really tell from Bosch's website.
Here's the Bosch "Premium" ... doesn't even talk about efficiency % ... but I think the boxes do have some kind of rating on them (?):

Here's the Bosch "Distance Plus", which shows the 99.9% efficiency and shows a red gasket like the PureONE.

My theory is that the Bosch Premium will become the Purolator Classic clone, and the Distance Plus will become the PureONE clone.
According to the web site, the Distance Plus will hold about 29 grams. The PureOne holds about 13 grams, per their web site. Probably both use similar media, hence the same 99.9% filtering efficiency. The Pureone site specifies at 20 microns, the Distance Plus site does not specify, as already noted.
Distance Plus might be good for those using ARX, MMO, etc for cleaning, in addition to longer OCIs.
Nice testing work, River Rat.
It is amazing the difference in what they are supposed to be able to hold
