Another thing you could use is the dust filter from modern computer boxes -

or you can use an open cell sponge thinly sliced,
or you can use medical guaze (any pharmacy)
The problem here is that the more effective your dust filter is, the faster it will clog, the more often you will have to clean it.Also, when it clogs it will reduce air pressure inside and plant s might get hot.You have to find a balance between thse 2 factors.
