He posted the Walmart super tech today and it allowed light through as well.
Assuming they are testing their filters legitimately to advertise the efficiency they do, I wouldn’t worry about it. The overwhelming majority of flow is going through the media. If it filters as efficiently as claimed, then it filters as efficiently as claimed.
Champion labs would be subjecting themselves to law suits from competitors who can and most surely do test the their competitions products.
Do companies find ways to beat testing in order to say their products are better than they really are? Hell yeah! Anyone would be naive to believe otherwise. I have no doubt they all do it but they better be able to reproduce the results.
Just like fuel economy claims. Auto manufacturers find ways to claim better fuel economy than we usually ever see.
If a guy changes his oil regularly and slaps a new filter on as often it ain’t gonna really matter much what oil or filter he uses so long as it meets specifications. Even the old tearing purolators did the job sufficiently enough.
That being said, it’s really dosent make a lot of sense to waste money on “premium “ oil filters like the subject filter.
