It doesn't "attract dust" the same way that electrostats do, probably true, but according to mr speakers people I've talked to it does attract dust more than dynamic designs, hence why they used a pretty dense dust cover on the ether. It also won't "shake loose" dust the way that a dynamic driver will, so the dust just accumulates. The motion of a dynamic voice coil will actually knock off dust particles somewhat if the voice coil is made of a non-charged material (most headphones are). Apparently this doesn't happen with planars.
You could probably use something like the hand powered blowers for camera sensors to clean them, and they probably wouldn't damage the diaphragm. It's not a gamble I would want to take, but it would probably be fine. You'd definitely screw stuff up with compressed air though.
I agree. The thin planar sheet can maybe build up a static charge too. Using a blower bulb would best be done with the bulb pointing at an angle to the diaphragm. Not blowing straight at it.
I have a tutorial for cleaning the dust off my electrostatic speakers that involves removing the frame with the diaphragm & giving it a shower bath. I never tried it, but know someone who did. Braver than me!
Guess it may be a good idea with the 400i to keep them covered when not in use if you are in a dusty environment.
