accurately evaluate them.
Hey, I'm chatty and always work from the premise that I am talking to friends so if that's irritating and you can't accept that, guess we're not friends and so don't know what to say.
As with anything I post, I am most eager and appreciative of any corrections, questioning, and even intuitions as to how it might be in error, incomplete or otherwise suspect. I don't value "winning an argument" as particularly useful but the recognition that I am/may be wrong and why are pure gold.
So, given that this is opinion and based on a number of premises:
My personal preference is the NoToil system. Others, including Uni and stock KLR are, IME, similar in effectiveness.
I evaluate by use of a light cotton cloth to wipe the air box and screen (if present) during air filter service in order to gauge the visible deposits of dust/dirt.
*It must be obvious that this does not reveal all materials getting past the filter element.
It is easy to fool anyone by appealing to "common sense" because "common sense" is simply that which agrees with what we already think. The less we know about a subject, the simpler it appears.
I prefer the NoToil because I found it to be simpler to service when traveling. Wash it out in the motel or washroom sink, leaving no mess at all, then let it dry over night and re-oil. Others which require solvents other than water are not so simple, IME.
One very powerful lesson which I always consider as the primary issue is the compatibility filter oil and the filter foam. Those who have experience using the older type NoToil filter oil (red bottle) on OEM KLR foam filters will know of which I speak. The oil/solvent would dissolve the filter glue and the filter would fall apart. This was really nice as it would seldom be noticed before the next service or, in cases of which I am aware, when the engine begins burning oil or fails to start because of low compression.
One can buy a lot of air filters for that cost.
I carry NoToil stuff and the recommended system for K&N (not a fan), as well as for Uni and Kawasaki foam in my garage. I try to avoid using anything but the oil recommended by the filter maker because I cannot evaluate the effects on the foam or whether a different oil than the one tested/recommended will be sufficiently effective.
I think one of the dumbest I've ever felt was when questioning whether one of my air filters "really needed replacement" or whether it could be used for another service or three.
Yeah, I know. Too dumb for words..... An all too common report is of a dusted engine because someone has not oiled the filter, left the basket out of the foam, not installed correctly, or the filter had a hole. First air filter clean on a new 250 MX 4 stroke at a friend's shop recently. Engine was capital "D", Done. Easily a couple of grand. Didn't oil the filter....not the first time the owner has done that on a bike.
That's about my take on air filters and service.
If someone can correct me, I'll be grateful.
Another point which came hard to me is to buy new filters every couple or three years and buy two. That way there's no rush to clean, dry and install. Pop out the dirty one, wipe check, grease the lip and in with the clean one. Clean, re-oil and zip lok baggie that one and ready for the next time.
An old friend once corrected me when I said that I had a tendency to be cheap. He suggested that "stupid" might be the preferable term.

Corrections not expected but eagerly and uncritically accepted.

Hate to ask but, are you oiling the foam filter and with the recommended filter oil? Any chance of a leak between the filter flange and the foam? Filter grease? Are you certain that the correct plastic filter support frame is inside the foam? I'd be phone Uni to consult. IME it is opposite, that the foam allows less dirt than K&N.
