How many Microns is it?
Also agree with the other posts here.
They claim a consistent pore size of 35 microns for the one in the original post. And there is only one or perhaps two layers of mesh between the dirty side and the "clean" side as best I can tell. That's how you reduce restriction and the need for a bypass valve, even the heaviest oil will blow right on through.
Micron ratings for oil filters are more smoke than factual information you can rely on. If you really want to know which filter is best at keeping crud out of the oil, you need to perform oil analysis after X number of hours and see what's still floating around in the oil. In other words, you need to determine actual filter efficiency, not what size the smallest pores in the filter media might measure. You might notice that none of the filter companies put that info on their labels. A truly informed consumer tends to screw up their ability to influence sales with misleading advertising.
The only engine in any vehicle I've ever owned that suffered an oil related failure was a car that used a metal screen instead of the modern spin on oil filters used these days. We called those things rock strainers back in the day, and that's what I still call these wire mesh filters today. Don't get me wrong, if they are done right they can be very efficient. For instance, the kind used in medical scenario's. But comparing the highly specialized and expensive stuff used in medical or even aircraft applications with the stuff being pawned off on the Harley market is disingenuous at best.
