Crack ANY vac hose next to your work, the VAC itself as far away as possible (outside if possible), so you can but a cheap non-static hose ext. Then you don't really care as it will just remove the fumes to stop you getting them. If you are in a workshop doing it, then just make up a hood over the area where you work with some ply with a hole in the top where you put the vac hose.
I would suggest a Y connector near your work area, so you can split where the suction is occurring from, you'll get more that way. Get a small smoke pellet (hardware store - oh, how american am I) and it will show you what's being extracted and what's not.
Equally, have a laugh and set a smoke pellet off in your house - amaze the neighbours as you open your front door and walk out as if a rock star entering the stage... Get the kids to hold torches on the floor, to really make the effects look super cool...
Oh.. no... I think I'm going to have a silly day now... I'm so glad I've got a warped mind !
p.s. make sure the kids wave the torches.
