I'm shopping for a new air filter for my 2019 Tacoma with the V-6 engine.
I've e-mailed several manufacturers (Denso, Fram, Wix, Hastings, etc.) and asked them, "Do you perform any ISO 5011 testing on your air filters? I'm specifically interested in any test data you have in regards to the PART NUMBER: xyz air filter.
Fram said, "Fram: ISO 12103-1 A4 coarse test (ISO 5011) - I show CA11895 to be 97.97% efficient using this testing."
I contacted Wix directly and they replied, "We do test our filters. However the test data we have is proprietary and is not shared. All of our filters will meet original equipment testing specifications."
To my surprise, I was surfing the NAPA Auto Parts website and found this filter (which says it's made by Wix) - https://napaau.to/38kn5q8 (Part #: FIL 200085) which says, " Air Filter Laboratory Tests Per ISO 5011 At Least 99.5% Efficiency (Based On NAPA # 2389)"
*I* think that's pretty efficient, which really appeals to me, but what does the comment ..."Based On NAPA # 2389"... mean, as it relates to the filter I'm interested in?
Thank you!
