Filters on alot of my heavy equipment specifically instruct to clean with compressed air. Guess some filters are built for it?
Rotate air filter every oci?

Looks almost exactly like the instructions for my big Hyster.
Here is what Mann says about blowing the air filter out(look at myth #6)

And this is from CAT, they don't even want you to open the filter housing to insepct it let alone blow air or tap the filter to try to clean it. They say to go by the air filter restriction gauge, nothing else.

Unfortunately those diagrams are still in a lot of manuals, although the Nissan dealer here covers them. Ignorance is king. You study filters enough you would never try to clean them, both from the media structure and the fact that the exterior dirt increases the surface area.

OK, some bad oil analysis results, claimed to be due to air filter cleaning (I assume with compressed air)
This is an interpretation of the results and, while it seems reasonable, doesn't seem to have been definitively proved.
There is a lot more there than oil analysis, but actual investigating and talking with the users who swear by cleaning "carefully"
And filters that are designed to be pulse cleaned are designed for surface load. The automatic systems shoot the pulse when the restriction goes slightly up. Once the frequency of the pulses gets too frequent (from saturation of the media), you change filters.

Ha! Brings back memories. I did this every summer on my 350 4 barrel. It was a great sound!

No they are cheap enough I just replace it with every OCI.

But did that make it measurably faster?

I've never even heard of this...

My buddy forgot to put it back on his dad's pristine 350/4 bbl - we had to take my old Ford for a month ...

I remember that.

I'm glad to know I'm no the only one who does this!

No, just sounded like it. What a roar!

As a reader, one can only go by what was posted. As I said, it seems reasonable, but it doesn't seem conclusive.
You've got some bad analysis results along with anecdotal evidence of filter cleaning. This is clearly a selected sample, and, on the face of it, it seems quite possible it is a biased one.
Are there similarly bad analysis results without evidence of filter cleaning, and if so how many cases?
Is there evidence of filter cleaning without similarly bad analysis results, and if so how many cases?
In the cases described, how carefully was the cleaning actually carried out?
Without that information one can't draw very firm conclusions.

I've probably got a thousand examples. Just last week someone came to me asking how he could possibly have oil consumption since he carefully cleaned his air filter every week. I see it over and over and over. Documented many times on my Spanish version of the site.
And many others who don't touch their filters until the restriction gauge hits orange who have practically no wear or consumption, including my Toyota T100 with more than 400,000 miles.
