Interesting Read About Oil Filters
went out and cut open just about every brand of oil filter to see the construction and provide feedback on their quality.

Conclusions
One thing should be pretty clear if you have made it through this entire article. While there are dozens of oil filter brands out there, there are only a few actual manufacturers. Most filters you see on the shelf are sold by companies that don't actually make oil filters. The exceptions are Baldwin/Hastings, Champ, Donaldson, Purolator, and Dana/WIX. Those are actual manufacturers and you can be fairly certain of what is inside the can. Although Fram hasn't made filters in decades, it seems that the brand is tied closely enough to Honeywell that you can be pretty sure about what is in the orange can (for better or for worse). Most other brands contract one of these companies to make filters for them. They seem to change from time to time, so one has to be vigilant when purchasing one. See the overview page for a quick manufacturer reference including images of their backplates.
If you want to hear my opinion take a look at the Oil Filters Revealed: Opinions and Recommendations page. Which filter is the best? There is no easy answer to that one. It depends on what kind of oil you use and how much you are willing to spend.
