Purolator P1 filters all have 99.9%, at an actual standard that can be compared, except for a small few and I'm sure Purolator will give you the efficiency on those.
What is this "standard" where every filter company is supposed to report at X efficiency and X microns? It doesn't exsist. Listing an efficiency at 99% at 20 microns has nothing to do with ISO 4548-12. ISO 4548-12 is
how they test the filter. There is no standard for how the data of the test is presented.
I'm not trying to convince you, people here, or anyone else that Wix is a better filter. Everyone should be using what works well for them. I'm not defending Wix, just laying facts that I know and that aren't advertising gimmicks. I've said countless times they're both great filters and I use whichever is on sale.
PureOnes may have higher efficiency / micron in some models versus a Wix but there's no way of knowing what every model has because if they published that data their advertising campaign would fall apart. As far as I can tell the data isn't readily available. Ultimately, who cares? Both are worth their price tags. A Wix at full price is just $0.49 more than the PureOne for my Honda application. In my opinion Wix has a better constructed filter which is probably why they charge slightly more.
You want to continue to assume all PureOnes are better simply for the type of media they use. That's fine, I don't care if they do or do not. The filtration difference is unbelievably negligible. It has nothing to do with that fact they're both quality filters.

When have I argued that Wix has had something else? I've only clarified this for you a few times. It's glass-enhanced paper media in Wix and a synthetic/cellulose blend in PureOne. This is common knowledge and easily found on both of their respective websites.

Well, now that you have your opinion can we move on?
