Have a box fan and, since not being satisfied with existing solder fume
filter because I have to be within 6" of opening, I purchased one of
these filters and placed across the box fan:

Appealed to me since it already has built in charcoal filter as well.
Won't be tested until this week. Thoughts?

When I was 16 I had a job in a TV factory. The PCBs were soldered by
floating them on solder baths. There was no sign of any smoke.
Soldering the components that had to be mounted by hand produced a
small amount gray smoke that was sucked up a vacuum pipe next to the
soldering iron. Almost everyone worked without the pipe because it got
in the way.
