The LF3487 is 100% at 24.6 microns apparently. Odd way of listing it, but there ya go, lol.
List of oil filters with 99% efficiency at 20 microns.

Yeah, but they catch quite a bit at the lower percentages. Like 10 microns at 80 percent. So I guess that's how it stands apart from the regular cellulose filters

Yeah, I assume it's like 99% or close to it at 20 microns was what I was getting at.

I believe you're correct. I think they're only ones that actually give a 100 percent rating. The micron size is much smaller below that percentage. I could have sworn it was 30 microns at 100 percent

They must have updated it, because back in 2023 it was 100% at 30 microns and 73% at 10 microns. So it's more efficient now, based on the figures on the website.

Good enough for me. I guess that's worthy of the $25 they charge

This is why I initially went to the fram ultras I think. Back then the filter was just as much as the oil once shipping was added in. The lovely $8.97 walmart price drew me in quicker than a honey bee on his first date.Good enough for me. I guess that's worthy of the $25 they charge

Years ago I bought a case of the Donaldson P169071 filters (same cross, 99% @ 22 microns with the Synteq media) for my Mustang and sold a pile of them to friends. I got a deal on them buying a case from what I Recall.
Would the Fram Endurance be the same 99% @ 20 microns BUT with better flow than the Fram Ultra ?
The Endurance would flow better than the NEW Ultra, with its' sprayed-on synthetic over synthetic blend media-but the older pink wire-backed OG/original Ultra would have similar flow & greater dirt handing ability due to the thick 2 layer all synthetic media. I like the Endurance, but the price is pretty steep for what you get, in my opinion.

It can, but if it’s a lot bigger (I.e. my use of the XG3600 in place of the 50%+ smaller XG4967 my Toyotas call for), or if there is depth media, a lot of syn media to trap debris, the higher efficiency can last longer. Knowing the engine’s limitations & cleanliness is good too…
I thought it was a major cheapskate move the first time I heard of it-then went & bought every OG Ultra & OG AAP Titanium I could find in the sizes I needed! Worst thing is, then the prices went up, & the leaf spring got ripples & the fiber seal disappeared!Sprayed on?I wonder how long it will take for THAT to come off

First Brands: First in cheapening the crap out of everything they touch.
Not necessarily, as it depends on the media design. Example: The OG Ultra and Titanium. You can have high efficiency, high holding capacity and relatively low dP vs flow performance. Total media area is also a factor.
On the other end of the spectrum there are filters that are rated for long use, but they are also low efficiency and let more debris go downstream as the load up slower.
right all others being equal, smaller miron rating=less life
All other what being equal?

But also rated in grams. Boss is an example, holds much more than the Red. If the Boss packs 32 grams in at 20,000 miles and a Red 13 grams at 10,000 which is more efficient? The Red is supposed to be more.
There is still the matter of circulations and particle concentrations. If you throw three golf balls at a green, probably none go in the hole. Throw 500 and probably at least one will find the hole.
Sure, a more efficient filter will build up debris faster than an inefficient one of the degris rate going into the filter are the same. ... I never implied they don't. I as saying that the general statement of "a smaller micron filter will clog faster" depends on a lot of other factors than just one media compared to the other on as square inch area basis. The exact design of the media - ie, it's fiber composition, thickness (depth filtering aspet), etc and the total media area can make a filter like the OG Ultra/Titanium high efficiency, high holding capacity and good flow (low dP vs flow). So it's a basic misconception that all high efficiency filters will "clog faster" ... it depends on all of the design factors put together. Look at Ascent's ISO testing graphs and the OG Ultra was the most efficient by far and had the 2nd highest holding capacity.
Bad analogy for oil filters. Good analogy for people that golf, lol.
