How to protect projector against dust?

[av_enthusiast@yahoo.com]

Greetings,
I had my BenQ PB6200 just returned from dust cleaning at BenQ's labs.
This projector is superb but has sensitivity to dust which results in
annoying white blobs when the picture is dark.

While BenQ's service has been superb and would clean the projector for
me for 3 years free of charge, I would like to avoid the hassle of
shipping it back and forth every time dust somehow reaches the
internals of the projector. I would like to be able to prevent dust
from entering the unit.

I am sure I am not the first one facing this kind of problem. So I am
curious to know whether anyone has succeeded in solving this problem or
whether there is a product out there that would alleviate the dust
problem.

Any tip or pointer would be greatly appreciated.

Thanks,
Victor

It seems to me that the best way to beat dust is to have a low dust
environment. I use a good quality vacuum cleaner and vacuum the carpet
and soft furnishings regularly.
