I'm not sure that my shop is 'shiny' but I have a LOT of light. The space is 12 x 14, lit by 4 - 48" LED units, 3 - 48" T-8's plus 3 task lights. So it's not so shiny but it is bright!
I just push the saw close to the bench so 1) the fan is as close as can be and 2) the light will reach.
The majority of scroll saw dust is under the table, as you'd expect. (They cut on the down-stroke and the gullets pull the dust through the stock and it falls off under the saw.) As you can see I have an Excalibur. And I know many Excalibur owners have chosen to remove the plastic at the throat because it gets in the way. I've learned to live with that in order to get better dust collection. In the picture, with this post, viewed from the back of the saw, you can see how the dust collector snakes around the saw.
I've used a few different filters over the years and IMHO the 3M filtrate filters work best. But for a small fan they'll have to be cut. And once cut, without the cardboard frame, they're hard to manage. I've thought about making a wooden frame, like I have on the box fan on the window sill, but haven't gotten around to it.
The filter on the small fan I have now doesn't seem to be working very well, I don't remember the brand. I picked it up because the size was better for the 12" fan.
