LOL
Don't think there is an issue with their oil filter media so much as poor spot welding... or glue blocking passages on some cartridges.
The reusable oil filter touted in this thread has a micron rating of 30 or 35 depending on which link is viewed.
Wix does better (25):

Did not find a rating for the Honda oil filter.
Be interesting to compare not only micron ratings but how much contaminants can be retained before the bypass opens and stops filtering.
I used disposable K&N oil filter cartridges on my last two Yamahas, after inspecting no ports were blocked by glue (had to send one back), primarily because I could order them at a very good price from O'Reilly Auto parts.
Thinking about helping my youngest son in law clean his k&N air filter on his F-150 last time I was in Arizona, there are other costs that showed associated with using a reusable oil filter or air filter:
In addition to time there is also solvents and cleaning up after the clean up!

Oil filtration has established standards:
ISO 4548-12 and SAE HS806 test standards are used by oil filter and Original Equipment (OE) vehicle manufacturers. These test standards specify over 15 different procedures to determine the performance and durability of an oil filter. Efficiency is a measure of how well the filter removes dirt from the oil.

We can fall into a rabbit hole on this one. Wix does not say their claims are verified according to established testing standards.
The ISO 4548-4 testing standard specifies: Initial Particle Retention Efficiency, Life & Cumulative Efficiency (gravimetric method).
Without the claim that their filtration specification is verified via a testing standard, we are left to trust the manufacturers claims. We are left to wonder whether the claim is for Initial Particle Retention (which degrades over the life of the filter), or over the "life" of the filter. What is the "life" of the filter? Different vehicle manufacturers have different recommendations as to oil change interval. For US, the life should be that interval. We cannot know what Wix, or anybody else says their filtration claim is, or what it is tied to. This is where we have the problem.
I cannot verify their claim, or the claim of the PC Racing filter.
I will claim I do not need any bypass system. Bypass should only engage when the filter gets clogged requiring it. If you have an event that causes your filter to prematurely clog, you have a much bigger problem than your oil filter. I will never allow my filters to clog because my oil change interval is (excessively) short, but it only costs me $20 and an hour of my time. Therefore, (For ME) I do not care what bypass is provided or not.
Yes, there is cost associated with solvents. Walmart sells a 12 oz can of carb cleaner for $2.50:

It might take 0.25 or 0.33 a can to clean the PC Racing filter. I do it over a pan outside so it does not stink up the garage and I don't breathe in the fumes. Then you need to dispose of it. My recycle center is very good, and they will swallow anything including used solvents and brake fluid. I can pour the pan contents into a used empty 5 qt (or whatever) oil container and recycle that when I also take the oil. The solvent might cost me $1. The actual cost of 4.1q of Mobil-1 is about $19, plus the $1 of solvent=my $20 per oil change cost estimate.
Since I cannot verify the claims of Wix, Honda OEM, or PC Racing filtration claims, I could GUESS that the Wix has a 40% better filtration efficiency, but it is only a guess because I don't know if any of them tested to this standard, and whether the claim is initial, over the life, or what the life is. You could ask Wix if their claim is based on testing to ISO 4548-4. It would be interesting to hear of their reply. I would also ask what 25 microns is, meaning what portion of the standard that number represents. Whoever answers the phone will probably have their head explode. I could also bother to ask PC Racing, but probably won't. If I change my oil with synthetic at 3K miles, my sense is that it won't matter very much. Let the flames begin!
Lastly, I am not really touting the PC Racing. I have no affiliation and will say (if you don't gather from above) that it is up to the potential user to decide for themselves whether they are any good or not at filtering, and whether they are at all cost effective. I don't work for them. I do think the filter looks good, seems to actually filter based on seeing what is on there when you clean it, and that it is convenient to not have to stock filters for changing oil. BTW, I will don gloves and eye protection before spraying any solvent out of a pressurized canister. You don't want any spray reflecting into your eyes or face. That is about all I will claim. It really takes no real additional time and not much effort to clean it while the oil is dripping from the sump. It is possible, that unit could actually cause harm because the filtration is not as good as it could be, if say compared to the Wix or OEM. I really don't know.
Lastly, I would be willing to bet that any (unsubstantiated) claims of filter efficiency (in microns), is likely the initial efficiency only assuming they use any established testing standard. After that, it is anybody's guess which one would be better at 1K, 2K, or 10K miles. Even if the DOJ forbid manufactures from making any claims unless they could prove through providing test data results to the standards tests, we still would not know which part of the standard their claim actually is. I would expect the initial value to be the best value, which is why I would bet that is what the claim is based on, assuming they did any testing to a standard and did not make up their own test standard.
