What is wix air filter efficiency?same as napa gold?

[ziggy]

Hi all! Been looking at air filters! Wix has a heavy duty air filter,rated 99.9% efficient.but,for a car,it's not applicable. I see on napas website, the gold air filter,everything the same as wix,is 99.5 efficient.
By comparison,pure one is 99%.20 microns?
What would be,wix,air filter efficiency?non heavy duty?

It's for a 98 buick lesabre.I have part number.I was curioys,about napa gold vs wix. One guy here,said he got a gold,short time in,it developed a hole.got a refund,but wix wanted too see filter.I know napa stuff is made in Poland alot.where wix is mostly USA made.wiz would be better quality,that wix made for napa.
So!wondered what wix air filter efficiency would be.for automotive,not heavy duty application.

I was watching project farms air filter test.wix,then pure One performed well,in his brief short tests.a.c. Delco.not bad.the rest,sucked.
