Ever since discovering the microgreen filters are not what they're claimed to be, I've spent a bit of time researching particle count results.
Firstly, I went to Dr Dave's Amsoil EA15K51 particle counts. He ran one filter for 22k miles and another filter for 43k miles.

From this, somewhere after 14.4k is when the particle count drops dramatically. At 14.4k, the ISO cleanliness code was 19/18/16. By 22k, it became 15/14/11 which is a big improvement.
The improvement lasts for a 20k miles or so which is excellent. But it was necessary to wait sometime after 14.4k miles to begin getting the benefit.
Compare this to btanchors particle counts with M1 filters.

At 5k miles, he got a cleanliness code of 16/15/13.
There is another case with an M1 and a FilterMag where the cleanliness code after just 2.5k miles was 15/14/12.

While the Ultra has tested in ISO tests as having very high filtering efficiency along with high capacity / life, it seems that high efficiency and lower capacity / life cellulose filters may in the real world end up producing lower particle counts and provide the benefit of that sooner.
With the M1 now 99% efficient at 30 microns, it may be that a ToughGuard or a PureOne, optionally with magnets, would actually be much more effective than a Ultra at reducing the real world particle counts.
