Actually WeirdEL if you have another look at the charts, the K&N was tested with both fine and coarse dust. It scored a 96.8% efficiency with the normal coarse dust and 89.85% with fine dust. It is still well below the significantly cheaper alternatives as far as filtering efficiency goes, although it has much better restriction figures than the others.
Oops! I'm the one that should have read the FINE print better! (Crawls away to hide under a rock somewhere...) :
