I can often extend the life of a paper filter simply by knocking off the loose dust from the exterior of the filter. (There's a lot of dust in my area.)
Has anyone messed with cyclonic dust removers? (I'm referring to a device that removes dust from the air like a Dyson vacuum.) I've heard of them, and seen some examples in heavy equipment, but not in passenger vehicles. Using a device of that sort before the air filter would certainly extend it's life, or even using a foam filter in front of the paper filter.
Reuseable filters are a good idea, but they need to be a bit more sophisticated than a porous collection of cotton fibers. I've seen some reusable filters in vacuum cleaners that are reusable, but look very similar to a traditional paper filter. I would love to have a reusable filter that i could trust, but the K&N variety is a type I don't trust.
