Activated charcoal ventilation

Thank you for the replies to my soldering location question the
other day. I have a second question tho! In my workshop it is going
to be impossible to vent the fumes to an outside source. I was
Googling soldering vents and came across some table top models that
use activated charcoal to clean the air. Does anybody have any
experience with these or an opinion if they will do the job or not? I
will be doing a minimum of soldering.Thanks in advance…

Activated charcoal is an mostly an absorbent filter. It is good for a
wide variety of contaminants but will also pick up things like water
vapor cooking oils and vapors auto exhaust residues. In short it will
try to remove all the vapors and fumes it can from the air not just
the soldering vapors and fumes. It will pick up all the fumes and
vapors it can hold and then it will stop working. The problem is it
will not let you know it is full and you will happily solder away
with no protection. Unless it is absolutely impossible to duct the
exhaust outside you should use external exhaust. If you must use a
ductless system set up a schedule for changing the filter and stick
to it. You still may be overloading the filter but at least it will
be doing its job part of the time.
