I manage to keep my sensor pretty clean. I have owned my Canon now for over two years and only have had to clean the censor about 3 times. I have found that the majority of the particles that get to the sensor are through the process of changing lens. Do you agree?
I keep a can of caned-air with me and use it to clean around the base of the lens and camera housing before changing lens, I find it to be effective. But here̢۪s my question.
If a high-end UV filter causes none or very little abbreviation or distortion to your photograph on the front-end of the lens, could the manufacture of the camera body find a way to have a screw on or push-and-lock filter made from the same high-end UV glass to be inserted into the camera body? It could be designed to insert between the lens and internal camera body inside the camera keeping the sensor sealed from particles that enter when changing lens. It would be a filter that could be removed by the photograph (just like removing a front-end filter) for cleaning and camera maintenance. It would mount to the body behind and inside the opening and not have anything to do with the camera/lens mount.
Just a thought.

Sigma kinda had this idea already, minus they werent great at it.
They put a piece of plastic in the opening.
1 - Dust on it is out of focus anyways so its not really a problem to an extent it wortks great.
2 - Sigma screwed it up badly, attahcment and all.
BUT
1 - Doesnt do anything for from the factory dust
2 - The camera needs to be dust sealed
Your fixed glass might work better though.
