I would not trust them unless they produce ISO 4548-12 test results. I don't think they did the tests. If they did the tests, why would they not release the results unless the filter flunked the test?
Curious, how do you know or are qualified to say what they did or didn't do?
Should I not trust Cummins? I have no 4548-12 from them.

In spite of everyones attempts to get ISO 4548-12 test results from them, they have never been successful getting any ISO test results. There is not one post made on BITOG backed by ISO 4548-12 test results.
Actually they have said it in emails to a few of us- as does Norb they claim that it is 99%@5M.
You didnt answer my question though.
