I had an old computer monitor box that I cut up and put a window box fan in as well as a florecent light, and used two A/C registar filters. I put this on a table in front of the window and use the fan to draw the exhaust through the A/C filters and out the window. On Low speed it works like a champ, and its light wenough to move into storage when I'm not using it. I used a box from a 21" monitor, but you can always go smaller. I model 1/32 alot or 1/72 bombers so I needed a big area.
I'm not sure how to post a picture but if you want to see it, email me.
