essentially a filter does a better job for you when it has dust in it as it traps more when it is fuller.
obviously when it gets too full it becomes too restrictive and could collapse so there is a point where it becomes dangerous. if you tap it and dust comes out easily, then that means it is full.
But the above is why the change interval is 30k. Up until that point it is keeping your engine clean and the manufacturer has designed the intake to be sufficient all the way up to 30k. Changing it too often means more dust gets through to your engine.
