Leo,
The plastic garment bag is indeed for drying film. If you buy the large
size typically used to store off season clothing, cut a few holes in the
bottom, then use plastic clothes pins to hang the film from the rail on
the top you will have a pretty dust free place to dry your film.  Hair
dryers can be rigged from the top to speed things up.

Ideally, purchase a dedicated filtered film dryer, but when you are
starting out on a budget then the garment bag is a very good compromise.
