Which air filter is best

best possible filtration
Well, the Titanium is the only one of those claiming 99% of filtration while the others don't claim that. However, I don't know for certain w/o micron size to accompany the percentage. I'd wager the Titanium is the best filtration out of them if I had to gamble.
The best air filter for your vehicle is the one that fits snugly when inserted - the bet I have found for my Hyundai was the OEM air filter . I previously tried a STP air filter but it let air in around the filter box causing high silicon readings on a UOA.
Are 4 flavors of the same sized air filter really necessary?
Wix, Fram , Purolator even SuperTech are fine. Just don't fall for the K&N hype.
A cheap paper air filter stops around 97% of dirt a good air filter does 99%. A great air filter does about 99.5% and the best do about 99.96%.
Supposed to be the most important filter in your car but not important enough to tell your the micron count it is rated at!
Sure makes you think they are shoveling something!

Yeah that's why of those I'd pick the one saying "99%". At least you know you're using a good air filter.
99% at what 2000 microns a good rock catcher. Microns is the defining point missing for most air filters.
They measure air filter efficiency very different than oil filters.
Air filter ratings use their own type of very expensive calibrated test dirt. Yes very expensive calibrated test dirt is a thing, see iso5011 testing. The test dirt has specific ranges of size from around 80 microns to I believe around 1 micron with most of the dirt being 20 to 40 microns in size. In an air filter you want to stop dirt down to about 2 microns in size, ideally even smaller than that. Where in an oil filter anything larger than about 15 to 30 microns is allowed to keep going.
Don't change the air filter until you are sure it full.

Air is a whole lot thinner than oil they need to tighten the spec. They all need to post it right on the box!
When wix screwed up their air filter build (they got rid of the metal screen) I went on a tear and bought like 8 brands.
I think the Denso looks best construction of all I bought.
The Fram Titanium looked OK also. It was the only Fram I bought, so I can't comment on the rest.

Yeah the air filter is the most important filter in the vehicle. What oil, oil filter and oci are meaningless without a good functional air filter.
