Ok so my tests are in and wow what an improvement. This is just a guesstimate but I'm looking at a reduction of maybe some 90% and maybe more. That's on looking at a 200MB scan at 100%.

So what did I do? This is with the addition of a Sears hepa filter (free-just put in new filters) and a facial steamer ($20). My MO is to run filter for about 20 minutes on low, turn it off and run the facial steamer. When that finished hang the film, keeping the film tray within a foot or so of the cabinet.

Thanks all for the tips and advice. I think the steam idea made a real difference.
