I've been meaning to test this so I've removed the air filter from one of my CX but just to help stop any cra*p can get in I've done this,

It's a piece of Tac-rag(Used in painting for wiping dust off the job) put over the Airfilter Top insert.Combined with the gauze filter in the airbox I'm happy to run the bike like this.Could use a bit of nylon stocking or similar as a filter)
Going to check it over the next couple of weeks and see
One of the things that makes me believe the air standard filters are a bit over-the-top is that people who have fitted,"Pod" filters don't worry and the pod's filters are nearly completely,"Air flow Transparent".
will most likely have to adjust mixture as well.
