Everything above is correct, never use them.
A manufacturer of said filters was on a magazine site and told us all how their test method was better than the multi pass rating method, so I looked up the ASTM test they used. (I have access to ALL ASTM and many many other standards)
It is a test designed for screening of filter material for consistency and comparison, nothing more.
Of no value in a real world filter where media depth is very important too.
Also, they come shiny, I don't like shiny. (see below)
As to cleaning them, NewHD47Fan nailed it, you cannot see the particles that we really care about, any cleaner you buy will likely have larger particles in it, still below eye range. So how do you clean with a dirty solvent? Remember, you can't see any of this.
-=-=-=-=-= End rant.
Rambling below.
SAE was paid years ago to run a study, 40 micron filter baseline (limit of human vision, btw)
A 30 micron filter cut wear by 50%
A 15 Micron filter cut wear by 75%
HD requires a 5 micron, whether that is nominal or absolute is a separate question that I struggle with, but I aim for high efficiency 5 micron or preserve my warranties. (gonna go to Amsoils eA0 next time since I found good data on them finally)
On chrome filters.
I am a bit of a filter snob, in addition to dealing with efficiency of filters (Beta ratings) with millions of dollars at risk, I also run the thermal imaging program here, so I gave the thermal end of the filters some thought. I don't buy chrome, not even for my wife's "too shiny to look at wonder Harley". I must be serious to tell her no, right?
Black will shed heat better than chrome. Given our bikes' propensity for hot running, why not give it every tiny benefit? May not matter, but I do it anyway. This is related to the emissivity of the surface, shiny and polished just doesn't emit heat as well as dull.
If you have one of those little temp buns, get it and a kitchen thermometer. Find a place to stick the thermometer and see what it reads, then shoot with the temp gun. If it is a shiny surface, you will get a lower reading. Unless you are seeing reflected heat from anything else, Shoot something cold and shiny outside on a sunny day, you will se hot. Shoot the sky on a hot day, you'll see cold. thermal is not really hard, but it is a different mind set.
The easiest way to get a good idea is to put a pan on the stove. Shiny outside w teflon inside.
Let it get hot and then hold it shiny side towards your face, feel the heat?
Now, turn the dark side towards you. It will feel much hotter. Even though they are the same temp on contact, Emissivity and radiant transfer at work.
Sorry for the rants
