Isn't the problem with the Toyotas that the air is bypassing the filter? Doesn't matter a tosh whether the filter works better clean or dirty, if the air isn't going through the filter in the first place!

From the same article by Ben Mullins “The issue here is probably the filter sealing rather than the filter itself, so disturbing the filter more frequently would likely make things worse. Proper tests would need to be done to see if the problem is the filter or the sealing, however flat panel filters can be difficult to seal, which is why heavy-duty engines generally don’t use them except for cabin air.”Quote:

Most aftermarket TD5 filters seal poorly letting too much crud past.
"When I get home I blow it out." Actually I do nothing of the sort (must have had a fit of age madness) ...... when I get home I use the vac. cleaner to suck it out the way it went in and the workshop (Aztech) renew it the 20K service intervals which they do while it's under warranty.
I clean it at the in between 10K service which I do myself.
Good filtration is like good oil and is cheap insurance as far as I'm concerned.

PS. On the Puma once, the stealers mechanics refitted the filter cover badly and it got drenched in a down pour when water poured off the wing into it. Luckily we hadn't been any where dusty after they'd "serviced" it.....
FWIW the air filter is far more important than the oil filter.
Anyone that's been anywhere near ag or heavy equipment had seen or heard tales of engines that have been dusted.
It only takes an hour or so in a dusty environment with an air leak to destroy the bores, rings and pistons, let alone all the other rotating and spinning bits.
I agree there Rick. That is why in certain areas of one mine I worked at we changed them twice a shift. They were big expensive filters which got sent to Perth for washing.
I also said about a BMW bike owner who didn't have a clue about servicing and he dusted his engine badly with a filter which was absolutely packed with dust as he used to ride into the site over hundreds of kays of dirt roads.
He told me "You shouldn't have to change filters on BMWs because they are an expensive bike......." He was a ****** in many ways actually.
