Premium Guard Ext Life - 99% at 25 microns, but micron rating is 42-60?

This 2013 Parts Plus version I received yesterday. 98% below 30 micron, multi-pass.

Was that an eBay purchase?

That was 12 years ago. Things probably have changed since then. The way they worded it is strange. Probably meant 98% at 30 microns and larger ... not "less than 30 microns".

Also, even today every brand under the PGI umbrella wouldn't necessarily all use the same media. Different brands could be stipulating different media specifications.

And the PGI type design hasn't really changed in 12 years.
