I have one of the carbon filter benchtop smoke removers under
discussion. Mine is a ‘Fume Trap’ by Inland, bought at a
stained-glass supplier for about $80.
It certainly appears to have good suction, and all visible 'smoke’
is being moved thru the carbon filter when I solder with paste solder
or liquid flux, but I can still smell fumes in the air.
Overall, I’d say it is much better than nothing, but not as good as
a hole-in-the-wall ventilation system. I have been using a shop vac
for this. Too noisy. I’m planning to set up the Fume Trap set up to
extract thru the wall.
If you can’t have a hole in the wall, you might be best to use a
fume- rated mask in addition to the Fume Trap.
