I get the dust, we're not talking minor sediment stir...
I have a leaf vac and what it does is suck up the leaves, shred them and blows them into a bag... The dust, which is really particles of leaves and dirt, comes out through the bags fabric and when it does it's EVERYWHERE, because with an 8hp engine it blows a TON of air. There's no getting away from it unless you plan on running some 'snorkel' all the way into another part of the yard like to the other side of the house or a good 10 or 20 feet away from the machine or straight up in the air because the cloud of dust engulfs the whole machine. We're not wearing dust masks because the air is clean a few feet above ground, even with the mask I have to be careful breathing because in great quantities that amount of dust can actually kill you... The entire machine and my body is covered in filth after about an hour or two of using that thing, and I mean caked, the stuff literally falls off, it's thick and it will turn washing machine and shower water BLACK it's so bad.
That kind of dust, sandstorm quality dust, it will choke a brand new air filter in an hour if it takes that long.
Best I can recommend is start looking for a washable filter such as a K&N
Or... Look for a filter in bulk quantities, they might be cheaper that way.
Another solution would be start using Pre-cleaners, those I do wash, once dirty I throw them in the washing machine, then let air dry.
What I've done before but you have to be careful, is spray it off 'gently' with compressed air.
You have to be careful and I won't guarantee that it won't tear the fabric, problem is we can't always see minor rips and tears but I blow at it sideways and just try to get the bulk dirt off, also gently tapping and banging the filter against a hard surface can help get some of the worst off... But I wouldn't wash it, not a paper filter.
