Filter recommendations for a LCD Projector to keep dust out..

[Michael Kennedy]

I've got a lcd projector that gets dust in it and I have to take it apart
and clean it every couple of months.. It has a thin electrosatic filter that
came with it but thats all. It is like a filter for a window unit AC.

Any ideas on something else I could use that would work better?
