This "k&n won't filter anything" is a myth, unsupported by any objective
scientific study.
Oil bath filters are great if they are serviced and you can put up with the
mess.
Since most of us aren't driving earthmovers, I'm pretty certain using a
spinning disc is overkill.

Say what????????????
For an off road vehicle your #1 choice should be an oil bath filter.
Your #2 choice should be a spinning prefilter in front of a paper filter (think
Donaldson earth mover 2 stage filter systems)
Your #3 choice a box of paper filters
Your last choice before no filter would be an oiled foam filter such as a K&N.
A k&N will filter out low flying birds, rocks, gum wrappers, small children,
but not fine dust. Them folks who get paid to race off road with K&N filters
completely rebuild the engine after each race. Breaths really well but foam
filters do not filter out fine dust. You can use one as a first stage to a 2
stage filter system but they are not as good as the spinner 2 stage systems.
