99%@25 microns per ISO 4548-12efficiency of around 96% at 20 microns
No read your picture 99% at 25 microns!
Yes. What I’d consider high efficiency.No read your picture 99% at 25 microns!
Why do these come out mint and others look like they’ve been ran over coming off the rampsPremium Guard PG2500EX with 6,500 miles. Made in Vietnam. It’s from a 2023 3.5 Ecoboost, engine has 27,000 miles

I don't recall any Premium Guard made filters every look bad ... maybe a few slightly wavy and/or uneven pleats, but nothing what I'd call "ran over".Why do these come out mint and others look like they’ve been ran over coming off the ramps![]()
The two efficiencies seen are 99%@25 iso 4548-12 and 99.5%@20(both great). After some serious digging on PG XL made filters both of these are actually correct. I completely understand the Vietnam concern. Unfortunately the quality of most USA made filters has tanked, accompanied by a price increase.25 micron at 99% is questionable as somewhere else they state very different micron ratings…
Also, not sure I am fan of “made in Vietnam”
But they do look good when cut!
I looked up my filter, and while it mentions numbers you quoted, in the detailed spec.The two efficiencies seen are 99%@25 iso 4548-12 and 99.5%@20(both great).

Several of us have emailed PG for an explanation. No response. My opinion is it’s the OEM spec which PG exceeds in this case. As a rule I personally look for ISO 4548-12.I looked up my filter, and while it mentions numbers you quoted, in the detailed spec.
Please explain what micron 42-60 means
