VAFI, Premium Guard, Carquest Premium, Microgard Select, Specs

Want to point out the part in bold. This is why some Premium Guard filters are made in China and some are made in Vietnam, because it looks like VAFI has a factory in both countries.

I think this is the China factory below. . You can see the building there with the same logo except for the C or G in front of the AFI

AFI stands for "Advanced Filtration Inc". Looks like a "C" to me, so the factory in Vietnam has VAFI (for Vietnam) and the China factory has CVFI (C for China).

Not from Vietnam (yet) ... but maybe the ones made in China.

Luckily for me it's the premium filters made in Vietnam that interest me.

It took me a long time to find this detailed efficiency graph. It’s been posted in a few threads now. Technically all the different efficiencies are correct. These filters are 99.8%@25 and 99.5%@20. How each company decides which to publish is beyond me.

I keep coming back to this post. Makes sense to me.

Buried somewhere is my post from when I called PG techline to get answers. The official ISO 4548-12 efficiencies are 98.7%@15, 99.5%@20, and 99.9%@25 microns.

I wonder if tariffs will make Premium Guard and related filters from Vietnam unavailable or unaffordable?

Last I heard the Vietnamese gov and Trump made nice. The Chinese were/are quite upset about it because they don't like Vietnam getting along with USA.

So probably Premium Guard (and other filters made by Premium Guard) won't be tariffed much, if at all.
